Abstract |
PURPOSE To evaluate of the mesopic vision and glare in normal subjects and post-LASIK patients by using mesoptometer. METHODS: One hundred sixty eyes of eighty subjects with normal vision and no ocular disease were divided into four groups. Each twenty subjects were followed up for more than 3 months and the authors tested the mesopic vision and glare disability with Mesotest II. The authors also measured eighty eyes of forty patients by same means depending on pupil size and high order root mean square (RMS) values before LASIK surgery in 1st and 3rd months postoperatively and compared with data of normal subjects. RESULTS: The mesopic vision and glare disability at 1: 5 contrast level were extremly reduced in the group over 60 age old but there was no statistical significance. In post-LASIK patients, mesopic vision and glare disability were significantly reduced in 1st month after surgery. However the values returned nearly to preoperative figures in 3rd month. Patients with large pupil and high order RMS values reduced more in mesopic vision and glare disability but there was not statistical significance. CONCLUSIONS: The mesopic vision and glare disability were reduced in older age group and they were reduced in the patients with large pupils and high order RMS values in the early postoperative period after LASIK. |
