Study Details

Study Description

Brief Summary

The purpose of the study was to compare the postoperative PCO results of the single-piece hydrophobic Acrylic IOLs versus the newer generation single-piece hydrophilic Acrylic IOLs in patients undergoing bilateral cataract surgery.

Condition or Disease Intervention/Treatment Phase
  • Procedure: Phacoemulsification
Phase 4

Detailed Description

Amongst several surgical techniques and IOL technology that influence the opacification of the posterior capsule, the role of IOL material and optic design remain crucial in determining its development. The single-piece Acrylic IOLs with a hydrophobic surface have been widely used in practice. The single-piece Acrylic IOLs with a hydrophilic surface became commercially available more recently. Although there is a study that compared the single piece hydrophobic and the single piece hydrophilic IOL, it was conducted on the older generation of the hydrophilic IOL. Moreover, experimental and clinical study has been performed to evaluate the posterior capsule opacification between the Hydrophilic acrylic IOL with a sharp optic edge design excluding the optic-haptic junction, versus the newer generation hydrophilic IOL design which has an improved 360-degree sharp edge, with results favouring the latter design. There is little data that compares the single-piece Acrylic IOLs with a hydrophobic surface to the newer generation single-piece Acrylic IOLs with a hydrophilic surface. Because the IOL characteristics play a crucial role to prevent posterior capsule opacification (PCO), it is of clinical importance, as well as investigational interest to assess the PCO following implantation of these IOLs. We conducted a prospective, randomised, intra-individual study to compare the 3 year postoperative PCO results of the single-piece hydrophobic Acrylic IOLs versus the newer generation single-piece hydrophilic Acrylic IOLs in patients undergoing bilateral cataract surgery.
