Comparison of Minimally Invasive Strabismus Surgery (MISS) and Conventional Strabismus Surgery Using the Limbal...

Area of Science:

• Ophthalmology
• Surgical Innovation
• Pediatric Ophthalmology

Background:

• Strabismus surgery aims to correct eye alignment.
• Conventional techniques involve larger incisions.
• Minimally invasive strabismus surgery (MISS) is an alternative approach.

Purpose of the Study:

• Compare minimally invasive strabismus surgery (MISS) with conventional strabismus surgery for horizontal recti.
• Evaluate functional outcomes and complication rates.

Main Methods:

• 40 patients with horizontal recti strabismus were divided into two groups: MISS and conventional limbal technique.
• MISS involved small keyhole radial cuts (approx. 1 mm smaller than muscle recession/resection).

Main Results:

• Significantly less conjunctival redness and swelling observed in the MISS group during the first three postoperative weeks.
• No significant differences in visual acuity, final alignment, binocular single vision, or other complications between groups after three weeks.
• Initial decrease in visual acuity on postoperative day 1 was not statistically significant between groups.

Conclusions:

• The described MISS technique using small incisions and minimal dissection is feasible.
• MISS demonstrates superiority in the immediate postoperative period due to reduced swelling and complications.
• Long-term functional results and alignment are comparable between MISS and conventional strabismus surgery.
