BACKGROUND: Two types of popular scleral tunnel sutures in the manual small incision @entity231 surgery (MSICS) are horizontal and X-pattern sutures. Surgically induced @entity940 (SIA) is a useful indicator of the suturing effect. AIMS: To compare SIA between horizontal and X-pattern sutures in the scleral tunnel incisions for MSICS. DESIGN: Prospective, nonrandomized comparative trial. MATERIALS AND METHODS: After superior scleral tunnel incision and capsulorhexis, the nucleus was prolapsed into the anterior chamber and delivered. The wound was sutured with either horizontal or X-pattern suture. The simulated keratometry values were derived from the corneal topography preoperatively and 1.5 and 3 months postoperatively. STATISTICAL ANALYSIS: The SIA was calculated by Cartesian coordinates based analysis. RESULTS: Sixty-four @entity1 (32 @entity1 in each group) were included in the study. In the horizontal suture group, the SIA centroid values at 1.5 and 3 months after the surgery were 0.87 * 1   and 1.11 * 180  , respectively, showing induction of against-the-rule @entity940 . In the X-pattern suture group, the SIA centroid values at 1.5 and 3 months after the surgery were 0.61 * 97   and 0.66 * 92  , respectively, showing induction of mild with-the-rule @entity940 . The difference between the amount of SIA at 1.5 and 3 months after surgery was small. CONCLUSION: In the MSICS, the X-pattern sutures were preferred to the horizontal sutures in the @entity1 without significant preoperative steepening in line with the central meridian of the incision. In the cases with significant preoperative steepening, sutureless surgery or horizontal sutures were preferred. Corneal @entity940 in the @entity1 undergoing MSICS was stable at 1.5 months after the surgery.
