Abstract

Aim: To compare refractive outcomes between optical biometer and immersion A- Scan biometry in senile cataract surgery.

Methods: 80 patients planned for cataract surgery were divided into 2 groups. Group A (40 pts) underwent biometry by IOLMaster-700 and group B (40 pts) by manual keratometry and immersion A- Scan. All pts underwent 2.8mm clear corneal phacoemulsification. The IOL material, design, and IOL formula were standardized. Postoperative refractive outcomes and error were compared.

Results: 45 F and 35 M with mean age 65.66±8.34 yr were included. The mean axial length in group A and group B was 24.48 ± 0.87 mm & 23.57± 0.85 mm respectively. Postoperatively, mean SE at 2 weeks was 0.01 ±0.65 D in group A and – 0.23 ± 0.75D in group B. Target refraction within ± 0.5 D & ±1.0 D was achieved in 92.5% and 95% pt in group A, and in 82.5% & 85% pts in group B respectively.

Conclusion: Biometry with IOL Master produces more accurate refractive outcomes than ultrasound biometry.
