Wearing contact lenses gives patients the flexibility and freedom to live life to the fullest, without some of the difficulties presented by wearing glasses. Many people who choose contact lenses do so because they don’t like the way that glasses look or feel, or because wearing glasses compromises their ability to perform certain tasks or activities, such as sports or jobs that require the use of safety goggles.
There are lots of different contact lenses to choose from, with two of the most popular being daily disposables and toric lenses.
As their name suggests, these daily contact lenses are disposable. This means that they can and should be discarded at the end of each day rather than re-worn. Disposable lenses do tend to be a little more expensive than some repeat-wear varieties, but the benefits usually outweigh the cost.
Some of the advantages of choosing daily disposable contact lenses include:
You don’t have to clean them, which saves patients a great deal of time and hassle. It also helps save money in terms of the ongoing cost of cleaning solution.
Disposable lenses are also great for people with eye allergies. This is because with ordinary lenses, there’s an opportunity for deposits and microorganisms to build up. With daily disposables, allergens have less chance to attach themselves to the lenses and cause irritation and other allergy symptoms.
You don’t need to schedule regular replacements either, which makes wearing contact lenses easier on your schedule.
Disposable contact lenses are particularly good for people who have busy lives and are likely to cut corners when it comes to caring for their eyes or contacts since there is no cleaning or maintenance required.
Daily disposable contact lenses are available in a wide range of prescriptions, including those for patients with nearsightedness and farsightedness. Your eye doctor will be able to advise you if you are a candidate for disposable contact lenses.
Toric contact lenses are recommended for patients who have a refractive eye problem called astigmatism. Patients with astigmatism have corneal abnormalities that cause the refraction of the eye to be different between the vertical and horizontal planes, causing blurred vision and difficulty seeing fine details. Toric contact lenses are shaped in a particular way that creates the different focusing powers needed in each part of the lens to correct your vision. For this reason, it’s essential that Toric lenses are placed into the eyes in the correct position. Fortunately, manufacturers design Toric lenses with features that help them to stay in place, including:
Creating areas of the lens that are thicker or heavier which helps secure it in position
An area where the bottom of the lens is slightly cut off
To keep them stable, Toric lenses are a little firmer than conventional soft lenses. This means that some patients can find them a little less comfortable, but the superior vision they obtain outweighs this. Your eye doctor will be able to advise you if you are a good candidate for Toric contact lenses and which variety would best suit you.

Every patient is different and so are their eyes. This means that there needs to be different types of contact lenses to suit each individual. Some patients have corneal abnormalities which mean that conventional lenses won’t sit comfortably on the surface of their eyes, while others suffer from eye conditions that mean normal contact lenses won’t be comfortable or could irritate their eyes.
As you may have guessed from the name, speciality contact lenses are unconventional contacts that are designed for patients that which regular contacts might not be suitable. Here are some of the main types of speciality contact lenses and who they are recommended for.
Some of the patients that might benefit from speciality contact lenses include those who:
have been diagnosed with dry eye syndrome
have corneal scarring
have been diagnosed with keratoconus, a condition characterized by the bulging of the cornea
suffer from strabismus, a condition where the patient has an eye that turns in or out relative to the other
suffer from a peripheral corneal thinning disorder
are intolerant to other types of lenses
Your eye doctor or contact lens provider will be able to tell you if you need speciality contact lenses and if so, which lenses would be best based on your individual requirements.
Also known as RGP lenses, these are made from special material that allows oxygen to pass through them and reach the surface of the eyes. This helps to keep the eyes hydrated and comfortable, making these lenses easier to wear, especially for patients who suffer from dry eyes. Dry eyes aren’t just a symptom, but a very real condition, characterized by dry, stiff and uncomfortable eyes, blurred vision and eye fatigue. RGP lenses are more rigid than soft lenses, and this helps to keep them stable and secure on the eyes so that patients can enjoy sharper vision. They also help the cornea to maintain their shape, which helps to minimize the effects of some corneal abnormalities.
Scleral contact lenses are very different to standard contact lenses. This is because scleral lenses are much larger in diameter, with three different sizes available depending on your specific needs. This size difference means that the edges of the contact lens fall on a white part of the eye, called the sclera rather than the cornea. Scleral lenses are also different in that they vault over the surface of the cornea rather than touching it, leaving a space between the front surface of the eye and the back of the contact lens. This makes scleral lenses a good choice for patients with dry eyes and corneal abnormalities. The space can trap tear film which keeps the eyes hydrated, while the space also accommodates many corneal abnormalities, such as the bulge associated with keratoconus.
Limbal contact lenses are another type of speciality lens that fall between rigid gas permeable lenses and scleral varieties in terms of their size. Their larger overall diameter helps to increase their stability on the surface of your eyes. They also offer minimal interference with the eyelids, which helps to ensure comfort and clarity of your vision.
Hybrid contact lenses are a combination of both soft and gas permeable contact lenses, giving patients the opportunity to enjoy the best parts of both designs. The middle part of hybrid lenses is made from gas permeable material that lets oxygen pass through to the eyes. However, the gas permeable part of the lens is more rigid, and this firmer center gives the lens greater stability and the patient enhanced clarity. The RGP portion of the lens also helps to trap a tear film between the cornea and the lens so that the eye remains hydrated. Meanwhile, the outer edge of hybrid lenses is a soft lens skirt. This means that patients don’t have to deal with the hard edges associated with RGP lenses that many be uncomfortable. Instead, the comfort levels that patients experience are more like wearing fully soft lenses.

We all want to look our best and in the last decade, we have seen a significant increase in the number of people seeking cosmetic services in order to enhance their appearance. With our eyes being our most distinguishing feature, we want to make the most of them. Thankfully there is now a range of cosmetic services that can help to rejuvenate our eyes and the area around them to keep them fresh, young and wrinkle-free.
Let’s take a look at some of the services on offer.
The brown pigment spots that appear on the face are often referred to as age spots and are a result of sun exposure. With age, the repeated exposure to UV rays causes melanin, a compound that is responsible for pigmentation and protecting the skin begins to clump together to form an area of hyperpigmentation. Whilst they aren’t any cause for concern, many people feel that they look unsightly. Luckily, there are a number of different treatments that you can get to remove them including topical creams, laser therapy, and chemical peels.
If you are suffering from darker pigmentation then we strongly recommend that you make an appointment with a qualified dermatologist who will recommend the best course of treatment for you, based on your specific needs.
If you are one of the thousands of people considering LASIK laser eye surgery, then you will probably be gathering as much information as possible about the treatment. By this point, you are probably aware of the benefits that LASIK offers, such as a reduced or eliminated need for glasses or contact lenses and greater convenience in your day to day life. However, for many patients, despite the advantages of LASIK, the thought of surgery on their eyes is still a cause of anxiety and fear. One of the best ways to alleviate this concern is to find out more about what the procedure entails.
Before you can be approved for any form of laser vision correction, including LASIK, you will need to attend a consultation appointment with your surgeon. During the consultation, he will perform an examination of your eyes and use your medical and ocular history to determine if you are a good candidate for the procedure. He will also speak to you about the expected outcome from your surgery, making you aware that while LASIK will dramatically improve your eyesight, there is no guarantee that you will not need to wear glasses in some situations, such as while driving in the dark.
LASIK uses a cool, ultraviolet beam of light to reshape the patient’s cornea. Doing so will more accurately focus the light that enters the eye on to the retina, thus improving the patient’s vision. The way in which the cornea needs to be reshaped will depend on the visual needs of the patient. For example, a patient who is far-sighted will need their cornea reshaping to be steeper to experience better eyesight. Alternatively, a patient who is near-sighted will require their cornea to be flattened in order to improve their vision. LASIK can also smooth an irregular cornea into a more standard shape, meaning that the procedure can also be used to correct astigmatism.
The LASIK procedure is very fast and straightforward. Although you will probably be in the surgical suite for around half an hour, the actual process only takes a couple of minutes per eye. The rest of the time will be spent preparing and ensuring that you are comfortable. Anesthetic eye drops are given to patients before their procedure so that the entire process is pain-free. If you are particularly anxious, it may also be possible for you to be slightly sedated – this should be discussed with your doctor at your consultation appointment.
Once you are in position, we will use a femtosecond laser to cut a thin, circular flap into the outer cornea. This can then be pulled back to reveal the underlying corneal tissue, known as the stroma so that it can be reshaped using the laser. The exact path that the laser needs to take, known as the topography, will have been pre-programmed ahead of the procedure and can be followed with complete precision and accuracy.
Once the reshaping is complete, the flap is replaced back over the eye and the surgery is complete. There is no need for sutures or bandages as the cornea will start to heal immediately and without any medical intervention.
If you already rely on wearing glasses or contact lenses to be able to see clearly, you may be frustrated with the effect that they have on your life. Regular vision tests, finding glasses to suit your face shape, having to remember to take eyeglasses with you wherever you go, prescription sunglasses, fiddly contact lenses… the list of inconveniences associated with conventional ocular solutions is extensive.
LASIK is a modern, minimally-invasive procedure that can substantially reduce or eliminate your need to use eyeglasses or contact lenses, allowing you to enjoy life without limitations or inconvenience. The popularity and success of LASIK laser eye surgery have helped to make it the number one elective surgery across the globe.
LASIK has an extremely high success rate. According to the American Society of Cataract and Refractive Surgery, 96% of patients achieve 20/20 vision or better. However, it’s high success rate doesn’t make LASIK automatically the right solution for everyone.
Candidacy for LASIK is assessed by our doctors on a case by case basis so that you be certain that whatever treatment is recommended for you, it will give you the very best opportunity to improve your vision. During your consultation, our doctors will perform a thorough examination of your eyes and vision, ask you about your general health and talk you through both the procedure and aftercare.
The general guidelines for LASIK candidacy state that patients must:
be at least 18 years of age
have had stable vision with no prescription changes for a minimum of 12 months
have a current prescription for eyeglasses or contact lenses that falls between specified parameters (Our doctors will be aware of what these parameters are)
have no significant medical or eye-related problems such as glaucoma, macular degeneration or diabetic retinopathy
have no history of corneal disease
not be pregnant or nursing at the time of the procedure
If you thought that just laser eye surgery was impressive, then be prepared to be astounded by the arrival of iDesign custom Lasik. iDesign is the most advanced wavefront-guided laser treatment available. The system creates a uniquely accurate measurement of the entire optical system that can be relied upon completely without any guesswork. This is then used to create a highly detailed topography or map of your eye, making it easier for your surgeon to pinpoint the areas that need addressing with pinpoint precision.
iDesign is extremely accurate due to its diagnostic equipment that is able to determine 1,257 different micro eye prescriptions. Each one of these will measure the eye prescription to 0.01 of a dioptre strength – 25 times more than what a regular prescription for glasses or contact lens prescription is measured to.
While iDesign Custom Lasik can benefit almost any patient with refractive problems, it is particularly beneficial for people who have unusual corneas or have had eye surgery in the past.
Laser eye surgery is generally considered a pain-free procedure by the majority of patients. Anesthetic eye-drops are used to numb the outer area of the eye during the course of the surgery. Once these have worn off, some patients do experience some mild discomfort during the days following the procedure, but over the counter pain relief is usually sufficient to relieve this.
Astigmatism is a relatively common eye disorder that causes the vision to be blurred or distorted. It occurs when the lens part of the eye, known as the cornea, isn’t perfectly curved and instead resembles a football rather than a soccer ball. This means that the light entering the eye comes through at a distorted angle, making the object appear blurry and out of focus. There are several ways in which it is possible to treat astigmatism, including laser eye surgery and corrective lenses. However, another possibility is a solution referred to as limbal relaxing incisions.
Limbal relaxing incisions are microscopic cuts to an area in the eye known as the limbus. This helps to relax the curve in the cornea and improve its ability to focus light correctly. It can significantly improve your astigmatism and the overall quality of your vision.
If you have astigmatism, are over 18, in good general health and have no major eye conditions, then chances are you are a good candidate for limbal relaxing incisions. Make an appointment with your eye doctor to discuss your candidacy further.
A refraction test, also called a vision test, is usually performed as a part of a routine eye examination. The purpose of this test is to determine if a person has a refractive error which would then mean the patient would need glasses or contact lenses.
A value of 20/20 is normal (optimum) vision. This means that individuals who have 20/20 vision are able to read letters that are 3/8-inch (1 centimeter) tall from 20 feet (6 meters) away. The normal uncorrected vision (without glasses or contact lenses) refractive error is zero (plano). Individuals who don’t have 20/20 vision, have what is called a refractive error. A refractive error means that the light is not bending properly when it passes through the lens of the eye. The refraction test will tell the doctor what prescription lens should be used in order to have 20/20 vision.
For people over age 40 who have normal distance vision but difficulty with near vision, a refraction test with a small type size is used to determine normal near vision and the correct power of reading glasses.
The test is performed by having the patient seated in a chair that has a special device (called a phoropter or refractor) attached to it. The patient looks through the device and focuses on an eye chart 20 feet (6 meters) away. The device contains lenses of different strengths that can be moved into the patient’s view. The test is performed one eye at a time. If the patient is wearing contact lenses, they should be removed before the test.
In case the final vision is less than 20/20 even with lenses, then there is probably another non-optical problem with the eye. The vision level achieved during the refraction test is called the best-corrected visual acuity (BCVA).
Abnormal results may be due to:
Astigmatism (abnormally curved cornea causing blurred vision)
Presbyopia (inability to focus on near objects that develop with age)
Other conditions under which the test may be performed:
Corneal ulcers and infections
Loss of sharp vision due to macular degeneration
Retinal detachment (separation of the light-sensitive membrane (retina) in the back of the eye from its supporting layers)
Retinal vessel occlusion (blockage in a small artery that carries blood to the retina)
Retinitis pigmentosa (an inherited disorder of the retina)
There is an art to refraction and the optometrist will always answer the patient’s questions and as well as discuss their findings. Based on the results of the refraction test, they can determine the amount of myopia, hyperopia or astigmatism.
The parts of a comprehensive eye examination vary according to the patient's age, date of last exam, and other factors. Not all parts of the eye exam may be needed or performed, but the first part of the eye exam will include documenting medical history. Here are some eye and vision tests that are likely to be encountered during a comprehensive eye exam:
Visual acuity tests measure the sharpness of vision and are usually performed using a projected eye chart to measure the distance visual acuity and a hand-held small acuity chart to measure the near vision (for reading).
A screening test that checks the color vision is often performed early in a comprehensive eye exam to rule out color blindness.
A test used to assess strabismus or a more subtle binocular vision problem that could cause eye strain or amblyopia (lazy eye).
Ocular motility testing is performed to determine how well eyes can follow a moving object and/or quickly move between and accurately fixate on two separate targets.
This is used to test perception of depth and 3-dimensional structure obtained on the basis of visual information deriving from two eyes by individuals with normally developed binocular vision.
This test is used to estimate which lens powers will best correct distance vision. Based on the way the light reflects from the eye, the doctor is able to obtain an approximation of the eyeglass prescription. This test is useful for children and patients who are unable to accurately answer the doctor's questions.
This is the test used to determine the exact eyeglass prescription.
When you were a kid, did you experience your eyes become reddish and all of a sudden, someone close to you was also suffering from it? Your eyes, as well as those who contracted it, got itchy and swollen, right? Then it must have been that you were suffering from pink eye.
Pink eye is well known as conjunctivitis and it is the infection or inflammation of the conjunctiva or the transparent membrane that serves as a covering for the white part of the eye called the sclera that lines the eyelid. In addition to inflammation, there is usually tearing in the eyes that emits a sticky discharge which develops into a crust while one is sleeping, making it difficult for the patient to open their eyes in the morning.
One thing about the pink eye, which could affect one or both eyes, is that it is highly contagious. While it is more common in children, adults can also victims of this eye condition. Here are the 3 major causes of pink eye:
Streptococci and staphylococci are bacteria types that are most responsible for pink eye. However, chlamydia and gonococci can also cause pink eye. It is accompanied by serious eye pain, itching, swelling, redness, and discharge. The spread of bacterial pink eye is usually as a result of using personal items of infected parties, such as makeup or makeup tools that have been infected with bacteria or putting dirty hands in the eyes. If not treated, it can last for more than 10 days, but if treated, it should resolve in less than 3 days.
Pink eye caused by allergies is followed by serious itching and tearing of the eyes. Pain is minimal, but it typically comes with quite a bit of discomfort. Most of the time, pink eye is accompanied by sneezing or coughing. Allergens that trigger pink eyes include grass, dust, pollen, mold, and ragweed. Allergy based pink eye is not usually contagious.
Viruses such as the adenoviruses and herpes virus are the most common causes of pink eye. When a virus is the cause, there is usually a lot of teary discharge accompanied by nasal congestion, puffy eyelids, runny nose, and sharp pain. It is usually contracted from cough and sneeze droplets from an infected individual. It can take as long as 2 weeks to treat depending on the seriousness of the infection.
General Symptoms of Pink Eye:
Redness of the sclera
Hazy or blurry vision
Oversensitivity to light
