Purpose
The aim of the study was to compare the post-cataract surgery spherical equivalent in patients who underwent non-mydriatic intraocular lens calculation and those who underwent cycloplegic intraocular lens calculation
Setting
University Hospital Center Zagreb
Methods
This prospective case-control study included a total of 47 patients divided into 2 subgroups that were age- and sex-matched.One group underwent preoperative biometry for IOL calculation without mydriasis, and the other in cycloplegia. IOL power was calculated by Zeiss IOL Master using the Barret Universal II formula. All patients underwent standard cataract surgery by phacoemulsification and were implanted with a monofocal IOL with a targeted residual refractive error of less than -0.50 dsph. After 4-6 weeks, patients were evaluated for residual refractive error subjectively and using autorefractor, which were than compared in both groups using spherical equivalent.
Results
The values obtained were normally distributed, so we compared them using the independent samples t test. The obtained P values (p=0,837 for subjective spherical equivalent and p=0,507 for autorefractive spherical equivalent) indicate that there is no statistically significant difference between these two groups in both subjectively determined spherical equivalent and spherical equivalent obtained by autorefractometer.
Conclusions
There isn’t a statistically significant difference in post-cataract surgery spherical equivalent (both subjective and autorefraction) in patients who underwent non-mydriatic intraocular lens calculation and those who underwent cycloplegic intraocular lens calculation.
