Avoid Lasik side effects

Side effects of Lasik eye surgery have prevented many from undergoing the procedure.

Take, for example a 37-yearold talent agent from Hollywood. He hated glasses and could not tolerate contact lenses. He even had the money to do the procedure. The only thing stopping him was that his uncle had the procedure 20 years earlier and had a lot of side effects.

This was food for thought, but it was also a lead-in to discussing how modern technology has decreased the incidence of side effects and the best way to prevent them.

The side effects from Lasik stem from causes before surgery, during the procedure and afterward. I explained to him that once we understand the cause, elimination becomes a matter of will and dedication.

Before surgery

Age of patient: The best age for Lasik eye surgery is from 21 to 45. Younger patients can undergo laser vision correction, but steps must be taken to determine stability of vision. Otherwise the effect of surgery will wear off.

Refractive stability: It is important that vision has stabilized and the eyeglass prescription has stayed the same for at least a year. However, minor variations are to be expected and are even allowed by the FDA.

Ruling out the effect of other medical conditions: diabetes and autoimmune diseases like thyroiditis may lead to increased side effects such as delayed healing of the surface layer.

Shape of the cornea: The shape of the cornea should be within normal ranges. If the cornea is thin or abnormal it could bulge after surgery, which would affect the outcome of the procedure.

Dry eye: This is present in a lot of individuals, especially those living in warm, dry climates like Southern California. Older individuals, postmenopausal women and anyone taking multiple medications are predisposed to a lack or poor quality of tears. Dry eyes must be resolved before Lasik is done.

During the procedure

Automated versus manual data entry: Manual entry for data needed to perform the surgery was found to be the most common source of error in one study. Newer automated wavescan systems eliminate data entry errors. The technology is used to collect information about the patient’s eye and create a correction plan to be used during surgery.

Calibration and accuracy of laser: Choosing a doctor one can trust is paramount because it is difficult to analyze behind-thescene actions. The best centers keep the laser well-calibrated and under maintenance contract with the manufacturing company.

Sterility of equipment: This is a no-brainer but is sometimes neglected at greedy centers.

After Lasik surgery

Immediate assessment of flap: Within an hour the surgeon needs to check the flap placement. Adjustments should be done to prevent long-term problems.

Doctor should check within 24 to 48 hours for inflammation or infection: This should not be neglected. It often gets omitted when the operating doctor is different from the one doing the postoperative checkups.
