Summary
Explaining and exchanging hydrophilic acrylic foldable intraocular lenses (IOLs) successfully resolved visual disturbances caused by optic transparency changes in 14 patients. This procedure improved vision and ocular condition.
Area of Science:
- Ophthalmology
- Biomaterials Science
Background:
- Hydrophilic acrylic foldable intraocular lenses (IOLs) can develop optic transparency changes.
- These changes can lead to significant visual disturbances and decreased visual acuity in patients.
Purpose of the Study:
- To describe the explantation and exchange of hydrophilic acrylic foldable IOLs.
- To evaluate the outcomes of this procedure in patients experiencing visual disturbances due to IOL opacification.
Main Methods:
- Sixteen hydrophilic acrylic foldable IOLs from 14 patients with visual disturbances were explanted using the bisection technique.
- The explanted IOLs were replaced with Acrysof foldable lenses.
- Complications such as posterior capsular rupture and vitreous loss were managed with anterior vitrectomy and IOL fixation in the ciliary sulcus.
Main Results:
- Successful explantation and exchange of all 16 IOLs were achieved.
- Visual acuity improved significantly in all patients post-exchange.
- No posterior segment complications were reported after the exchange procedure.
Conclusions:
- The explantation and exchange of hydrophilic acrylic foldable IOLs using the bisection technique is a successful procedure.
- This surgical approach effectively resolves visual disturbances caused by IOL opacification and improves the ocular condition.
