Summary
Intrascleral fixation of implantable capsular hooks offers a stable and safe method for in-the-bag intraocular lens (IOL) implantation in eyes with subluxated lenses, improving visual acuity.
Area of Science:
- Ophthalmology
- Surgical Techniques
- Intraocular Lens Implantation
Background:
- Subluxated lenses pose surgical challenges for standard intraocular lens (IOL) implantation.
- Capsular support is crucial for stable IOL placement and optimal visual outcomes.
Purpose of the Study:
- To evaluate the clinical outcomes of intrascleral fixation of implantable capsular hooks for managing subluxated lenses.
- To assess the feasibility, stability, and safety of this surgical approach.
Main Methods:
- A prospective, non-comparative, interventional case series.
- Included patients with subluxated lenses undergoing in-the-bag IOL implantation with capsular tension rings and implantable capsular hooks.
- Assessed IOL position, visual acuity, refractive outcomes, endothelial cell density, and complications.
Main Results:
- Seventy-four eyes were followed for a mean of 13.2 months.
- Stable IOL position was observed with minimal decentration (0.31 mm) and tilt (1.83°).
- Best-corrected visual acuity improved significantly (P<0.05), and refractive outcomes were favorable. Corneal endothelial cell density showed a mean decrease of 14.70%.
Conclusions:
- Intrascleral fixation of implantable capsular hooks is a feasible, stable, and safe technique.
- This method facilitates in-the-bag IOL implantation in eyes with subluxated lenses.
- The approach leads to improved visual acuity and stable refractive outcomes.
