Summary
Limbal relaxing incisions (LRIs) effectively reduce corneal astigmatism during cataract surgery. This simple technique offers a forgiving approach with no overcorrections observed.
Area of Science:
- Ophthalmology
- Corneal Surgery
Background:
- Astigmatism is a common refractive error impacting visual acuity.
- Cataract surgery presents an opportunity to address coexisting astigmatism.
Purpose of the Study:
- To assess the efficacy of limbal relaxing incisions (LRIs) in correcting corneal astigmatism.
- Evaluate LRIs as an adjunct to standard cataract surgery.
Main Methods:
- 12 eyes of 11 patients underwent cataract surgery combined with LRIs.
- LRIs were performed using a modified Gills nomogram.
- Preoperative astigmatism was measured via keratometry and videokeratography.
Main Results:
- Mean preoperative keratometric cylinder was 2.46 D.
- A mean reduction of 1.12 D in keratometric cylinder was observed at 1 month.
- With-the-wound (WTW) change was -0.70 D, with minimal axis shift and no overcorrections.
Conclusions:
- Limbal relaxing incisions provide a practical and simple method for astigmatism correction.
- LRIs are a forgiving technique during cataract surgery.
- This approach effectively reduces pre-existing corneal astigmatism.
