Abstract :Objective: The study aimed to evaluate the effect of cycloplegia on the ocular biometric parameters and intraocular lens insert ignore into journalissuearticles values(IOL); power calculated by Sanders–Retzlaff–Kraff/Theoretical insert ignore into journalissuearticles values(SRK/T); formula in the cataractous eyes. Materials and Methods: This cross-sectional study included 68 senile cataractous eyes of 68 patients scheduled to undergo cataract surgery. Measurements of anterior chamber depth insert ignore into journalissuearticles values(ACD);, axial length insert ignore into journalissuearticles values(AL);, white-to-white insert ignore into journalissuearticles values(WtW); diameter, keratometry insert ignore into journalissuearticles values(K1, K2, Kmean);, central corneal thickness insert ignore into journalissuearticles values(CCT);, and pupil size insert ignore into journalissuearticles values(PS); were obtained with AL-Scan insert ignore into journalissuearticles values(Nidek Co., Ltd, Gamagori, Japan); before and after cycloplegia. The SRK/T formula was used to calculate IOL power with target refraction of 0 D. Cycloplegia induced by cyclopentolate hydrochloride %1. Results: The mean age of the patients was 70.60±4.07 years insert ignore into journalissuearticles values(range 65 to 80);. A significant increase was observed in ACD after cycloplegia insert ignore into journalissuearticles values(p< 0.001);. There was no statistically significant difference between pre-dilation and post-dilation AL, WtW, CCT, K1, K2, Kmean, and IOL power readings insert ignore into journalissuearticles values(p> 0.05);. Two cases observed a decrease above 0.5 D of IOL power after cycloplegia. Conclusions: Cycloplegia induced by cyclopentolate hydrochloride %1 does not affect the measurement of the AL, WtW, CCT, keratometry, and SRK/T calculated IOL power except ACD in senile cataractous eyes.
