Summary
Intravitreal phacoemulsification effectively removes dislocated lenses with vitrectomy, offering a safe alternative. This surgical approach significantly improves visual acuity in patients with posterior lens dislocation.
Area of Science:
- Ophthalmology
- Surgical Techniques
- Retina
Background:
- Posterior lens dislocation can result from ocular trauma or intraoperative complications.
- Management of dislocated lenses requires specialized surgical techniques to restore vision and prevent complications.
Purpose of the Study:
- To evaluate the efficacy and safety of intravitreal phacoemulsification for removing posteriorly dislocated crystalline lenses.
- To assess visual outcomes and postoperative complications following this surgical approach.
Main Methods:
- Retrospective analysis of 22 cases with posteriorly dislocated lenses.
- Procedure involved total vitrectomy followed by phacoemulsification of the dislocated lens without a silicone sleeve.
- Simultaneous management of intraocular foreign bodies, retinal photocoagulation, and intraocular lens implantation was performed.
Main Results:
- Successful extraction of all dislocated lenses without severe complications.
- Significant improvement in corrected visual acuity post-surgery (P <0.05).
- No retinal detachment, hemorrhage, or scleral wound burn observed; secondary glaucoma cases showed controlled intraocular pressure.
Conclusions:
- Intravitreal phacoemulsification combined with vitrectomy is an effective and safe treatment for posteriorly dislocated lenses.
- This technique presents a viable alternative to phacofragmentation for managing dislocated lenses.
