Abstract

Background: To evaluate the variation in K-readings after application of artificial tears of different viscosities in mild to moderate dry eyes.

Design: Cross-sectional comparative study.

Methods: Setting: A tertiary care centre in Mumbai.

Patient or Study Population: Patients presenting with cataract in our OPD were screened for dry eye disease and 50 eyes of 30 patients with mild to moderate dry eyes were recruited for the study.

Observation Procedure (s): Baseline keratometric measurements were taken followed by Instillation of low viscosity artificial tears and repeating keratometry at 1 minute and 5 minutes after instillation. Then high viscosity artificial tears were instilled after 24 hours and keratometric measurements were taken at 1 and 5 minutes after instillation. Main Outcome Measure (s): variation of K-readings at 1- and 5-min interval after application of artificial tears compared to baseline.

Results: Instillation of both low and high viscosity artificial tears resulted in statistically significant changes in K1 measurements in both mild and moderate dry eyes at 1- and 5-minute intervals compared to baseline (p>0.05). However, K2 and axis did not show significant changes in both mild and moderate dry eyes.

Conclusions: The variations in K1 after the instillation of artificial tears can potentially confound IOL calculations and affect surgical outcomes. Clinicians should be mindful of these effects when interpreting keratometry data
