evaluate the clinical outcomes of routine CTR insertion in conjunction with hydrophilic versus hydrophobic IOLs following phacoemulsification.

Full description

Phacoemulsification with intraocular lens (IOL) implantation is the standard surgical approach for cataract extraction. The choice between hydrophilic and hydrophobic IOLs has been debated, with studies suggesting differences in posterior capsule opacification (PCO) rates and capsular bag stability. Capsular tension rings (CTRs) are devices designed to stabilize the capsular bag, particularly in cases with zonular weakness. While CTRs are beneficial in complex cases, their routine use remains controversial. Understanding the interaction between CTRs and IOL materials could inform surgical practices and improve patient outcomes
