Aim: to compare the clinical accuracy between ultrasound and optical biometry
Material and methods: prospective comparative study was conducted on 200 randomly selected patients diagnosed with cataract without underlying pathology visited the department of Ophthalmology, Patna Medical College and Hospital, Patna, Bihar, India. Group-1 IOL power calculated by optical biometer (N=100) and Group-2 IOL power calculated by ultrasound biometry (N=100).
Results: mean age of the study population was 60.21 years. Majority of the patients affected with cataract were female. Group 1 showed better visual outcome postoperatively than compared with ultrasound A scan in Group 2 (p≤0.05).
Conclusion: concluded that optical biometry with the AL scan (Nidek) found to be more accurate than ultrasound biometry for IOL power calculation
Keywords: AL scan, Biometry, IOL
