Summary
Transscleral fixation of posterior chamber intraocular lenses (IOLs) improved vision for most patients. However, complications like macular edema and retinal injury can impact visual recovery.
Area of Science:
- Ophthalmology
- Surgical Techniques
- Intraocular Lenses
Background:
- Posterior chamber intraocular lens (IOL) implantation with transscleral fixation is a surgical option for various ocular conditions.
- Indications include aphakia, posterior capsule rupture during cataract surgery, and management of retained lens material or dislocated IOLs.
Purpose of the Study:
- To review the outcomes, complications, and fluorescein angiographic (FA) findings in eyes undergoing transscleral fixation of posterior chamber IOLs.
- To evaluate the efficacy and safety of this surgical technique.
Main Methods:
- Retrospective review of 18 patients who underwent transscleral fixation of posterior chamber IOLs.
- Assessment of visual acuity, intraocular pressure, and IOL position (decentration and tilting).
- Iris and retinal fluorescein angiography (FA) performed in 14 patients.
Main Results:
- Mean best-corrected visual acuity improved from 20/70 preoperatively to 20/30 postoperatively.
- 14 out of 18 patients achieved visual acuity of 20/40 or better.
- Complications included cystoid macular edema (6 eyes), epiretinal membranes (5 eyes), and light-induced retinal lesions (6 eyes).
Conclusions:
- Transscleral IOL fixation can provide adequate visual acuity for many patients.
- Macular edema and epiretinal membranes may contribute to incomplete visual recovery.
- Light-induced retinal injury represents a significant irreversible intraoperative complication.
