Who is a good lasik surgery candidate?
Many factors are involved to ensure a patient is a proper lasik surgery candidate.
First, their current glasses prescription should be stable. Surgeons recommend it be within +/- 0.50 for 2 years or more. If a patient is considering a major life change such as going back to school for a new degree or a possible pregnancy, Lasik surgery should not be pursed until a later date. Life events such as those mentioned can cause glasses prescriptions to change. Dr. Dryer prefers a patient be 26 or 27 before they pursue Lasik. Prescriptions tend to continue to change well into the 20s today with computer use.
Secondly, they must have a glasses prescription that falls within safe corrective measures. Those with high prescriptions or high amounts of astigmatism may not qualify; however, they may be candidates for a corrective intraocular lens surgery. Patients with a history of Keratoconus, significant dry eye or other cornea disease may also not qualify.
Most importantly, the cornea must be a particular thickness for excellent results. The higher the beginning glasses prescription, the more thick the cornea must be for safe results.
What is the lasik surgery evaluation process like?
The initial pre-op lasik evaluation includes: corneal health evaluation, dry eye evaluation, prescription check, corneal thickness measurements, and a dilated exam.
If determined to a good candidate, patient will be referred to a refractive surgeon for further testing. Corneal maps and measurements will be taken for best post-Lasik surgery outcomes.
What should I expect after Lasik surgery?
After Lasik surgery, the vision should continue to improve the next several days. You will be seen the day after surgery, a week after, a month after, and 3 months after surgery.
The most common side effects after surgery are dry eye and halo effect. However, these side effects continue to improve up to 3-4 weeks after surgery.
Patients will be instructed to use an antibiotic and steroid drops after surgery for the first week. A gel tears should be used as frequently as possible to improve both vision and comfort for several weeks after surgery.
Will lasik surgery improve in the future?
As with any surgery, results vary per patient. One should never go into elective surgery expecting to never wear glasses or contacts again. This is not a realistic expectation.
The last significant improvement was made several years ago with an improved laser. We have not seen any significant changes in the post-surgery outcomes, but a slight decrease in post-surgical halo effect.
Many technological advanced have been made in the eye care field. Researchers are using both stem cells and 3d printing correct both health and diseased eyes. These areas of research may become the new standard in correcting eye prescriptions.
