Summary

This study evaluates how preoperative ocular hypotony (Goldmann IOP ≤ 7 mmHg) affects refractive predictability, axial length measurements, and visual outcomes in patients undergoing combined phacovitrectomy with silicone oil for rhegmatogenous retinal detachment.

Conditions

  • Rhegmatogenous Retinal Detachment
  • Hypotony Ocular

Interventions

PROCEDURE

Combined Phacovitrectomy with Intraocular Lens Implantation and Silicone Oil Tamponade

Standardized single-stage clear corneal phacoemulsification with IOL implantation is combined with three-port 25-gauge pars plana vitrectomy, fluid-air exchange, endolaser photocoagulation, and silicone oil tamponade for rhegmatogenous retinal detachment. After cataract extraction and IOL placement, pars plana vitrectomy is performed with fluid-air exchange to reattach the retina, endolaser photocoagulation around retinal breaks, and tamponade with silicone oil.

PROCEDURE

Silicone Oil Removal

Silicone oil removal is performed approximately 3 months after the initial combined phacovitrectomy. Three-port 25-gauge pars plana access and pressure-controlled fluid-silicone exchange with balanced salt solution to completely remove silicone oil from the vitreous cavity. At the end of surgery, sclerotomies are sutured.
