Comparison of Accuracy of IOL Master and a Scan Acoustic Biometry in Silicon Oil Filled Eyes

Objective: Objective of our study was to determine accuracy IOL Master and A scan acoustic biometry in silicon filled eyes terms mean difference axial length pre-operatively post-operative refractive error Study design: Comparative cross sectional settings duration: conducted at department Ophthalmology (Eye Unit III) Mayo hospital Lahore (KEMU) from November 2019 April 2020. Material methods: WHO calculator used for calculation patient sample (N=34). Patients were randomly divide two groups Group I underwent preoperative (AXL) measurement by using a-scan ultrasound Siliconized mode. Results: Total 34 patients included study. There 18(52.9%) male 16(47.1%) female. Mean age 44.2±6.4 years. undergone with showed better visual acuity (Log Mar) (0.25±0.7, 0.63±0.09, p=0.000), less (0.22±0.02, 0.72±0.17, p=0.000) as compared those which done. significant reported (p=0.04) Conclusion: master is more accurate reliable method power resulting outcomes eyes.
