Part of the work up prior to undergoing refractive cataract surgery is a thorough retinal examination. The retina is the tissue that lines the back of the eye. It acts much like the film in a camera by processing light that is focused on it so that you can see clearly. The centre of the retina is called the macula. The macula is responsible for central vision, the part of your vision that is most responsible for important daily activities of life such as reading, writing and driving. Diseases of the macula can lead to reduced central visual acuity. In some cases, cataract surgery can lead to a worsening of macular disease, as in diabetes. Therefore, if you have any ... Read More
A cataract is a natural clouding of the lens of the eye – once it affects vision or quality of life, your eye care professionals may refer you to a laser eye surgery for cataract. During surgery, once the natural cloudy lens is removed, an intraocular lens (IOL) is implanted to allow patients to see. During this consultation, various IOL options would be discussed, including the pros and cons of each. Depending on the type of IOL chosen, this will affect where the focal point of vision is and whether a patient may need to wear glasses to optimize their vision for various distances. Patients who desire less dependency on glasses for distance and near work may opt for a ... Read More
Before undergoing refractive eye surgery or LASIK, it is important to have a complete ocular examination. This includes an examination of the retina. The retina is the tissue that lines the back of the eye. It acts much like the film in a camera by processing light that is focused on it so that you can see clearly.
It is important that the retina remains attached to the back of the eye for it to function. Lesions in the peripheral retina such as retinal holes or tears, or lattice degeneration, may lead to retinal detachment if not addressed, particularly before any surgery is undertaken.
Lattice degeneration is a thinning of the retina that can predispose to retinal holes or tears. ... Read More
Near-sightedness, is a type of refractive error that is also known as myopia. Individuals usually wear spectacles or contact lenses to correct their distance vision. Some myopes often remove their glasses for near tasks, and others leave them on or wear bifocal glasses. The correction of myopia is one of the most common reasons for individuals to undergo laser vision correction – so that distance correcting glasses or contacts can be eliminated altogether.
In the past, patients with large myopic prescription (high myopes) often were not candidates for laser vision correction. However, with major advancements in laser technology and techniques, high myopic corrections are now a possibility. To determine if you are candidate for laser vision correction, a thorough screening ... Read More
Contact lenses are a wonderful way to correct refractive error (need for prescription vision correction) and have changed many thousands of individuals’ lives. They do however require very special care and attention to prevent complications that can be sight threatening.
Soft lenses are much more popular than rigid (hard) lenses because of their easy comfort. It’s important to limit wear time to 8 hours or less per day if possible; this allows the cornea to ‘breath’ and recover. Symptoms of overwear include discomfort, redness and frank pain on removal of the lenses. Overwear also makes the eyes more susceptible to infection, a sight threatening complication.
Cleaning and care of contact lenses is crucial to safe use. Remember that this includes ... Read More
Laser vision correction is a procedure that refers to the correction of ones refractive error to eliminate or reduce ones need for spectacle correcting glasses or contact lens wear. By applying a laser to the cornea, either below the corneal epithelium or lasik flap, most refractive errors can be corrected. Fortunately, with significant advancements in technology – complications are uncommon.
The most common sensation individuals feel after the procedure is dry eye – which in some cases can be transient (weeks to months) and in other cases can be long term. Fortunately, whether the symptoms are mild or severe, there is escalating treatments that can be effective in managing dry eye. Although the refractive results are durable, and depending on ...

Several factors may affect long-term vision stability in LASIK. If your glasses or contact lens prescription have remained the same for at least two years prior to LASIK, then you are more likely to have stable vision after the procedure.
Those patients who have very high prescriptions for near sightedness, far sightedness, or astigmatism may have a higher rate of regression (that is the initial effect of LASIK may wear off over time). Regression usually takes place within the first 6 months of a LASIK procedure. After an enhancement procedure, long-term stability of vision will likely ensue.
Some patients may have "soft corneas" or even require treatment for undiagnosed keratoconus during their screening exam. In the past, these cases would ... Read More
LASIK (laser in situ keratomileusis) and PRK (photorefractive keratectomy) are both commonly used to remove or reduce the need for spectacle use. LASIK at our facility involves the creation (by laser) of a partial thickness flap in the cornea (the clear window at the front of the eye) and then further laser application to the corneal bed to reshape the cornea and thus reduce spectacle prescription. This is all laser driven and no blade is used in this procedure at UELC; thus accuracy is excellent. Patients have minimal discomfort after LASIK and have excellent vision from day 1 although this will improve further over the next few days.
PRK reshapes the cornea using the same laser without creation of the ... Read More
Have you ever thought to yourself, “I would love to get LASIK done…. I just can’t afford it!” But here is a fact -- having laser vision correction not only helps to get rid of the inconveniences of wearing glasses and contact lenses, it can also save you a lot of money. Laser eye surgery is an investment, and the lifetime cost savings can add up quickly. For example, the average cost of contact lenses per year is $200, even more if you have astigmatism. Then you add the cost of contact lens solution which is about $150 per year. In 15 years, a person paying this average price would spend $5250! More than the cost of laser refractive surgery! ...
