Biometric Findings in Patients Undergoing Cataract Surgery; Gender Comparison

Purpose: To report normal biometric findings in patients undergoing cataract surgery and make comparison of these values between males and females. Study Design: Cross sectional, descriptive. Place and Duration of Study: Data collected in Armed Forces Institute of Ophthalmology (AFIO) Rawalpindi during 2016 was analyzed. Material and Methods: A total of 752 biometeries were done in patients undergoing cataract operation. Axial length (AL), Keratometry readings (K1 and K2), Anterior chamber depth (ACD) and Posterior chamber intraocular lens power (PC IOL) of the patients were assessed to find mean, standard deviation, minimum value and maximum value. Statistical analysis was done in SPSS 20. Comparison of these values for males and females was done by Independent Samples t Test. Results: Age ranged from 16 years to 105 years (Mean 63.05 10.52). Male were 412 (54.79%) and female were 340 (45.2%). Mean AL was 23.22 1.08 mm. Mean K1 was 42.87 1.98 D. Mean K2 was 43.96 1.8 D. 4.55. Mean ACD was 3.2397 .40 and mean PC IOL was 21.2 2.35. Significant differences were observed in all the parameters when the findings for males and females were compared. Conclusion: Pakistani female cataract patients have smaller axial length and anterior chamber depth but higher corneal curvature when compared to their male counterparts. Keywords: Axial length of eye, Keratometry, Intraocular lens.
