应用VISULYZE生成Nomogram辅助SMILE矫正近视散光的短期效果
The short-term effect of using VISULYZE generated nomogram to assist SMILE for myopia and astigmatism correction
摘要
Abstract
Objective To evaluate the short-term efficacy of the VISULYZE software generated nomogram in assis-ting small incision lenticule extraction(SMILE)for the correction of myopia and astigmatism.Methods Non-randomized controlled trial.Patients who underwent SMILE surgery with the original nomogram,assisted by the same surgeon at the Laser Myopia Treatment Center of Xi'an NO.1 Hospital between February 2023 and January 2024,were included.A total of 52 patients(102 eyes)of myopic astigmatism with 3-month postoperative follow-up were collected.VISULYZE software was then used to generate a new nomogram.Subsequently,a total of 40 patients(70 eyes)with myopic with-the-rule astigmatism and a preoperative cylinder of ≤2.00 D,who underwent SMILE assisted by the new nomogram at the same center between August and November 2024,were enrolled.Among them,50 eyes had a target refraction of plano and were assigned to the experimental group.In addition,from the database of patients who underwent SMILE assisted by the origi-nal nomogram,42 patients(70 eyes)with myopic with-the-rule astigmatism and a cylinder of ≤2.00 D were screened,of which 51 eyes had a target refraction of plano,and these were assigned to the control group.The postoperative visual and refractive outcomes of both groups were compared at 3 months.Astigmatism results were analyzed using Alpins vector analysis.Results At 3 months postoperatively,among eyes with a target refraction of plano,50 eyes(98.0％)in the control group and all 50 eyes(100.0％)in the experimental group achieved an uncorrected distance visual acuity(UDVA)of ≥ 20/20.No eye in either group experienced a loss of more than one line in corrected distance visual acuity(CDVA)compared with the preoperative level.At 3 months postoperatively,63 eyes(90.0％)in the control group and 66 eyes(94.3％)in the experimental group had a spherical equivalent(SE)within-0.50 to 0.50 D.The postoperative cylinder was significantly lower in the experimental group than in the control group(P＜0.05).Vector analysis revealed that the ex-perimental group had smaller values for the difference vector,index of success,and absolute angle of error than the control group,with all differences being statistically significant(all P＜0.05).At 3 months postoperatively,43 eyes(61.4％)in the control group and 57 eyes(81.4％)in the experimental group had an angle of error within-5° to 5°.Conclusion The use of the VISULYZE software generated nomogram can optimize SMILE surgery design,offering good efficacy,safety,and predictability,and improving the precision of SMILE surgery for correcting myopia and astigmatism.关键词
