Can the enhancement rate following laser vision correction be lessened in the future?
From the standpoint of the physiology of the eye, the enhancement rate for refractive surgery can be reduced in the future, but it will never be zero. Why? The answer is a math problem. Enough variation exists in the human eye’s response to laser vision correction that there will always be variance in the result by either over-or under-corrections. In this regard it is better to under-correct a patient than to over-correct. So, if you had the expected variance of the human eye’s response to treatment and know that under-corrections are slightly better than over-corrections from both the clinical and patient perspective, then the enhancement rate will never be zero. If you consider enhancements from the vision standpoint, the answer is still yes. As time goes on, clinicians are becoming more astute about which patients should have — and are most likely to benefit from — enhancement procedures and which are not. That is to say, the ultimate goal of refractive procedures is to produce goo
