Purpose:
To describe and evaluate the feasibility of a novel pars plana vitrectomy (PPV) technique for the removal of retained lens material (RLM), which obviates the need for either 20-gauge intravitreal fragmentation or perfluorocarbon-assisted elevation.
Methods:
Interventional case series. After thorough 23-gauge PPV, the hard lens material is engaged and held adherent to the vitreous cutter using aspiration, then raised into the anterior chamber. There, a standard phacoemulsification probe, inserted through a corneal incision, is used to fragment and remove the material.
Results:
Three eyes of 3 patients were operated on. In all eyes, RLM could be removed completely. Postoperatively, 2 of 3 eyes (67%) achieved 20/20 best-corrected visual acuity. No complications such as glaucoma, cystoid macular edema, corneal edema, or retinal detachments were recorded. Intraoperatively, retinal tears were detected in 2 of 3 (67%) eyes and treated with endolaser retinopexy and fluid-air exchange. One eye subsequently developed macular hole requiring further surgery.
Conclusion:
Suction-assisted lens elevation may be a viable and convenient technique to remove RLM during PPV. Although the comparison with other methods is beyond the scope of this preliminary study, visual outcomes and complication rates were encouraging and should be validated in a larger group of patients.
