Pterygium size and effect on intraocular lens power calculation

PURPOSE: To evaluate the effects of pterygium on biometry measurements and the relationship between these effects and pterygium size. SETTING: Ulucanlar Eye Hospital, Ankara, Turkey. DESIGN: Prospective comparative study. METHODS: Patients who had unilateral primary pterygium excision were included in the study group. Anterior segment photographed images were taken of eyes with pterygia to calculate the pterygium length and area using the ImageJ program. Preoperative and 3-month postoperative biometry measurements (Lenstar LS900) were obtained for eyes with pterygium and their healthy fellow eyes (control group). RESULTS: created at least equal to or more than 0.5 D deviation in the IOL power calculations. CONCLUSION: and simultaneous surgery is planned, the implanted IOL power should be at least 0.50 D smaller than the calculated power.
