EFFECT OF CYCLOPLEGIA ON CORNEAL BIOMETRICS AND REFRACTIVE STATE

Abstract

Introduction

Cycloplegic agents have diagnostic and therapeutic applications. A thorough assessment of the anterior segment is crucial for corneal refractive surgery, diagnosis, and follow-up. The objective of this study was to compare pre- and post-cycloplegic measurements in both eyes to assess the effect of cycloplegic agent instillation on anterior segment parameters such as spherical power (SPH), cycloplegic refraction, and keratometric readings (K1, K2), as well as gender differences in these changes.

Methodology

This cross-sectional analytical study was conducted in the Department of Ophthalmology, Paf Hospital Islamabad, from 1st January 2024 to 30th June 2024. Patients with clear ocular media and normal anterior segment morphology were eligible for this study. All subjects got a baseline anterior segment examination. Data was  stored and analyzed using IBM SPSS version 23.0.

Results

The results showed large increases in spherical power after cycloplegic refraction, as well as a significant drop in the steeper keratometric value (K2) following cycloplegia in both eyes.

Conclusion

Cycloplegia causes large increases in spherical power and decreases in steep keratometric readings among juvenile patients. The findings emphasize the importance of cycloplegic evaluation in juvenile refractive assessment
