VISX PRK VS. VISX LASIK
Postoperative stability seems to be slightly better after PRK than after LASIK. Although,
preoperative Spherical Equivalent (SphEq) and Intended SphEq correction were statiscally
higher in eyes treated by LASIK than in eyes treated by PRK.

Patient satisfaction after LASIK
A questionnaire that included 8 questions related to postoperative satisfaction was
distributed at last follow-up visit in the LASIK study. Patients were instructed to answer
“yes” or “no” to the questionnaire. Response rate to the questionnaire was 86%. All
respondent reported that they would have LASIK surgery again and that they considered
that LASIK surgery had improved their quality of life substantially. Eighty-nine % were
very satisfied with the surgery but only 55% were currently happy with their refractive
status. Eleven % complained of visual performance in daylight and 39% complained of
problems in dim light. Thirty-three % reported experiencing “tired eyes” in the past last
month and 33% reported dry eye. Fifty-seven % did not wear corrective spectacles, 16%
wore them occasionally, and 27% used spectacles for distance vision every day.
