目的:评估和比较三种不同的人工晶状体(IOL)植入方法在半脱位性白内障手术中的临床效果。
方法:在本回顾性研究中,比较,临床介入研究,接受无缝线27号针辅助经结膜巩膜内人工晶体植入术患者的医疗记录(第1组),经巩膜Z型缝合无结(第2组),在2010年6月至2022年6月期间,对Cionni囊膜张力环(Cionni-CTR)辅助(第3组)同时进行了半脱位性白内障摘除术的评估。人口特征,后续时间,非矫正视力(UDVA),矫正视力(CDVA),球面和柱面折射率值,比较3组的球形当量(SE)值。记录术中、术后并发症。
结果:第1组20只眼,第2组35只眼,第3组40只眼。在所有组中,术后UDVA和CDVA与术前相比有统计学意义的改善(均P<0.05).术后UDVA和CDVA值组间无统计学差异。(p=0.130,p=0.167)。两组间术后球性无显著差异,圆柱形,和SE值(每个p>0.05)。
结论:研究表明,三种不同的IOL植入技术在半脱位白内障手术中同时植入IOL对视力和屈光结果的影响相似。
OBJECTIVE: To evaluate and compare the clinical outcomes of three different methods of intraocular lens (IOL) implantation in the surgery of subluxated cataracts.
METHODS: In this retrospective, comparative, clinical interventional study, the medical records of patients who underwent IOL implantation with sutureless 27-gauge needle-assisted transconjunctival intrascleral (Group 1), Z-suture knotless transscleral (Group 2), and Cionni capsular tension ring (Cionni-CTR) assisted (Group 3) simultaneously with subluxated cataract extraction between June 2010 and June 2022 were evaluated. Demographic characteristics, follow-up times, uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), spherical and cylindrical refractive values, and spherical equivalent (SE) values of three groups were compared. Intraoperative and postoperative complications were recorded.
RESULTS: There were 20 eyes in Group 1, 35 eyes in Group 2, and 40 eyes in Group 3. In all groups, statistically significant improvement was observed in postoperative UDVA and CDVA compared to preoperative values (each p < 0.05). There was no statistical difference between the groups in postoperative UDVA and CDVA values. (p = 0.130, p = 0.167 respectively). No significant difference was observed between the groups in terms of postoperative spherical, cylindrical, and SE values (each p > 0.05).
CONCLUSIONS: The study suggests that three different IOL implantation techniques for simultaneous IOL implantation in subluxated cataract surgery have similar effects on visual and refractive outcomes.
