Retinal Complications Post Posterior Chamber Phakic Intraocular Lens Implantation At A Tertiary Eye Hospital In The Eastern Province Of Saudi Arabia

This study aims to report the incidence and risk factors of retinal complications after posterior chamber PIOL implantation and assess the differences in biometric parameters between patients who developed such complications versus those who did not.

This retrospective study recruited 514 patients who underwent ICL implantation to correct myopia at a tertiary eye care center in the eastern province of Saudi Arabia from January 2014 to December 2019

This retrospective study

Retinal complications occurred in six cases (1.2%) where five had retinal detachment, and one had a macular hemorrhage. The mean (SD) axial length was 27.3 (1.9) mm with a range of 26.4 to 34.5 mm, and the mean (SD) pre-spherical equivalent before ICL (pre-SEQ) was -10.6 (3.8) with a range of -1.7 to -23.7 .

The incidence of retinal complications was 1.2% of cases (6/512), five cases had retinal detachment (1.0%) and one case had macular hemorrhage (0.2%). Mean (SD) age was 25.33 (±5.7) years, ranging from 20 to 33 years.  

The mean (SD) axial length was 28.8 (±0.85?) mm with a range of 28 to 32.2 mm, and the mean (SD) pre-spherical equivalent (pre-SEQ) before ICL was -15.18 (±3.0) with a range of -10.5 to-18.3. 

the incidence of retinal complications was 1.2%. Patients with high axial length and high pre-spherical equivalent before ICL are at high risk of retinal complications.
