Introduction : Intraocular lens implantation is a treatment of choice in cases of aphakia. Aphakia conditions with minimal or no capsular support can use the anterior chamber LIO technique, iris, sulcus, and scleral fixation. The retropupillary iris fixation technique is an alternative technique that is often chosen by operators in aphakia caused by minimal complications and good visual outcomes. Purpose: to describe visual acuity and complication after secondary iris claw retropupillary intraocular lens implantation in patients with aphakia. Method: this research was a descriptive study by taken data from medical records at Undaan Eye Hospital Surabaya on January 2019 to Desember 2020. We observed the outcome visual acuity and complication from first day until 3 months after surgery. The population in this study was all aphakia patients who had secondary retropupillary iris-claw IOLs implantation surgery that fulfilled the inclusion criterias. Results: This study found that from 19 subjects, dominated by male (57,90%). The age group consisted of 49-76 years old, mean 59,05 years old. The most common cause of aphakia was lens subluxation (78.94%) as a result of previous cataract surgery. The complication found was a surgical induced astigmatism (52.63%).
