Abstract
Introduction: Minimal access surgery is common in all fields of
medicine. We compared a new minimally invasive strabismus
surgery (MISS) approach with a standard paralimbal strabismus
surgery (SPSS) approach in terms of post‑operative course.
Materials and Methods: This parallel design study was done
on 28 eyes of 14 patients, in which one eye was randomized to
MISS and the other to SPSS. MISS was performed by giving two
conjunctival incisions parallel to the horizontal rectus muscles;
performing recession or resection below the conjunctival strip
so obtained. We compared post‑operative redness, congestion,
chemosis, foreign body sensation (FBS), and drop intolerance (DI)
on a graded scale of 0 to 3 on post‑operative day 1, at 2‑3 weeks,
and 6 weeks. In addition, all scores were added to obtain a total
inflammatory score (TIS). Statistical Analysis: Inflammatory
scores were analyzed using Wilcoxon’s signed rank test.
Results: On the first post‑operative day, only FBS (P = 0.01)
and TIS (P = 0.04) showed significant difference favoring
MISS. At 2‑3 weeks, redness (P = 0.04), congestion (P = 0.04),
FBS (P = 0.02), and TIS (P = 0.04) were significantly less in MISS
eye. At 6 weeks, only redness (P = 0.04) and TIS (P = 0.05) were
significantly less. Conclusion: MISS is more comfortable in the
immediate post‑operative period and provides better cosmesis
in the intermediate period.
