The cornered incision--a precision cataract wound.

Area of Science:

• Ophthalmology
• Surgical Innovation

Background:

• Cataract extraction is a common procedure.
• Managing post-operative corneal astigmatism is crucial for visual outcomes.

Purpose of the Study:

• To evaluate a new cornered incision technique for cataract extraction.
• To assess the impact of this technique on residual corneal astigmatism and visual rehabilitation.

Main Methods:

• One hundred fifty-four patients underwent cataract extraction using a new cornered incision.
• Closure was performed with 10-0 nylon sutures under keratometric control using the Terry surgical keratometer.

Main Results:

• 79% of patients achieved 1.50 diopters or less of residual corneal astigmatism at two months.
• The technique allowed for precise suture placement and wound closure.
• No instances of suture cutting were reported.

Conclusions:

• The cornered incision facilitates accurate wound closure in cataract surgery.
• This method leads to reduced residual corneal astigmatism and rapid visual rehabilitation.
