Abstract
The implantation of an intraocular lens (IOL) is the gold standard in today's cataract surgery. Calculating the power of the intraocular lens (IOL) has emerged as a central concern in cataract surgery over the last decade. The study aims to investigate the relationship between optical biometry and applanation ultrasound measurement of the eye's axial length. This prospective cohort study was done on 60 eyes from sixty patients undergoing phacoemulsification with primary intraocular lens implantation and scheduled for cataract surgery in the Ophthalmology Department of al-Imam al-Sadeq Hospital. Thirty eyes of patients were measured by ultrasound measurement (by A-Scan, Group 1) and the other thirty eyes by optical biometry (by IOL Master, Group 2). In Group 1There were 14 eyes of 14 males (47%) and 16 eyes of 16 females (53%) with a mean age was 71.6 ±4.33years. In Group 2, there were 16 eyes of 16 males (53%) and 14 eyes of fourteen females (47%), and the mean age of the patients in this Group was 66.13±8.61 years. The mean IOL of the patient in Group I was (19.96±1.81). At the same time, the mean IOL potent ion of the patient in Group II was (22.96±1.66).
