Summary
Scratched MemoryLens surfaces occurred in two patients due to small incisions and excessive force during implantation. Rounded forceps and a 3.8 mm incision are recommended for safe thermoplastic lens implantation.
Area of Science:
- Ophthalmology
- Biomaterials Science
Context:
- Thermoplastic intraocular lenses (IOLs), such as MemoryLens, are increasingly used due to their foldable nature.
- These lenses are implanted through small incisions, unfolding within the capsular bag.
Purpose:
- To report a complication involving scratched anterior lens surfaces after MemoryLens implantation.
- To identify the cause of the complication and provide recommendations for prevention.
Summary:
- Two cases of scratched MemoryLens anterior surfaces were observed after phacoemulsification and implantation in 35 patients.
- Scratches resulted from excessive pressure and mechanical force from forceps during insertion through a slightly too small corneal incision.
Impact:
- Highlights the risk of surface damage to thermoplastic IOLs during implantation.
- Recommends specific surgical techniques, including using rounded-tipped forceps and ensuring an adequate incision width (3.8 mm), to prevent IOL damage.
