Corrective Lenses after Refractive Surgery

Even with the best techniques, a specific visual acuity can never be guaranteed. However, most people with low to moderate nearsightedness and astigmatism can achieve excellent results after refractive surgery. In many studies, more than 94 percent of patients with low to moderate nearsightedness will achieve 20/40 or better uncorrected vision after refractive surgery.

With 20/40 or better vision, a person should be able to pass the driving vision test without wearing corrective lenses in most states. For most people, this level of vision would be adequate for the majority of their everyday activities. However, for special situations (such as night driving) in which the sharpest vision is desirable, some people may still want or need to wear glasses or contact lenses with a mild correction.

Additionally, people who are 40 or older may still require glasses for reading. In fact, presbyopia, the normal aging of the eye that often results in the need for bifocals or reading glasses, is common. Those who are nearsighted before refractive surgery may still need reading glasses after refractive surgery as they approach the age of presbyopia — usually 40 to 45 years of age.
