Summary
Clear corneal incision size increased after implanting two AcrySof intraocular lens (IOL) models during phacoemulsification. Modifications to the MA30BA model resulted in a smaller wound size compared to the MA60BM model.
Area of Science:
- Ophthalmology
- Surgical Technology
- Biomaterials Science
Background:
- Phacoemulsification is a common cataract surgery technique.
- Intraocular lenses (IOLs) are implanted to restore vision after cataract removal.
- Clear corneal incisions are crucial for wound healing and visual outcomes.
Purpose of the Study:
- To evaluate clear corneal incision size variation in phacoemulsification surgery.
- To compare incision size changes after implanting two AcrySof IOL models (MA60BM and MA30BA).
Main Methods:
- Prospective study of 108 eyes undergoing phacoemulsification with AcrySof IOL implantation.
- Quantified wound incision size using the Nordan incision size measurer.
- Analyzed incision size before and after IOL implantation and its relation to complications.
Main Results:
- Mean incision size increased significantly after IOL implantation for both MA60BM (3.7mm to 3.9mm) and MA30BA (3.3mm to 3.4mm) models.
- No association was found between final incision size and intraoperative complications.
- Difficulties during IOL implantation were noted in 23 eyes.
Conclusions:
- Incision size increases post-implantation of both AcrySof IOL models studied.
- The modified MA30BA model demonstrated a 0.5mm average decrease in wound size compared to the MA60BM model.
- Most implantation difficulties were linked to improper IOL unfolding, not incision size.
