OBJECTIVE: This study aims to evaluate the clinical effectiveness of combining lentectomy, vitrectomy, and trabeculectomy in treating secondary glaucoma caused by lens dislocation.
METHODS: We retrospectively analyzed data from 20 cases (20 eyes) of traumatic lens dislocation accompanied by secondary glaucoma. The patients underwent standard 3-port pars plana vitrectomy and the upper trabeculectomy. Mitomycin C (MMC) was applied below scleral flap during surgery. We evaluated preoperative and postoperative visual acuity, intraocular pressure (IOP), and any complications.
RESULTS: Postsurgery, visual acuity improved in 18 of the 20 eyes (90%). The operation was considered successful if postsurgery, the use of topical antiglaucoma drugs was no longer necessary or reduced, and the IOP was controlled within the range of 6-21 mmHg. Of the cases studied, 18 eyes (90%) had a successful outcome, while 2 eyes (10%) were unsuccessful, with an IOP of less than 6 mmHg. All 20 eyes (100%) developed follicles postoperatively. Complications included intraocular hemorrhage in 3 eyes, low intraocular pressure in 6 eyes, choroidal detachment in 4 eyes, and hyperfiltration in 2 eyes.
CONCLUSION: The combination of lentectomy, vitrectomy, and trabeculectomy presents a safe and effective method for reducing intraocular pressure and improving visual acuity in patients with secondary glaucoma resulting from lens dislocation.
