Purpose:
This study reports the clinical results of sutureless intrascleral fixation of posterior chamber intraocular lenses (PC IOLs) in eyes without capsular support.
Methods:
Thirty patients without capsular support who underwent standard 3-piece foldable PC IOL implantation using the sutureless intrascleral fixation technique were studied retrospectively. Folded PC IOLs were injected through corneal incisions, with 2 haptics piercing out from 2 corresponding scleral punctures, which were 1.5 mm from the limbus and exactly 180° to each other, and then 2 haptics piercing respectively were placed in 2 corresponding limbus-parallel intrascleral tunnels. All patients were evaluated for preoperative and postoperative status and complications.
Results:
During the follow-up period, the visual acuity of all 30 patients significantly improved, with that of 21 patients improving by more than 0.6. The intraocular pressures of all patients were stable. All PC IOLs were stable and centered. Optical coherence tomography revealed that the haptics were located within the tunnel. Other complications, such as IOL dislocation, endophthalmitis, and retinal detachment, were not detected.
Conclusion:
Sutureless intrascleral fixation is safe and effective for the implantation of PC IOLs in eyes without capsular support from a variety of causes.
