目的:使用改良Yamane技术和瞳孔后虹膜爪型人工晶状体(RPIOL)植入的无缝线巩膜固定人工晶状体(SFIOL)植入患者术后1年,使用Scheimpflug角膜地形图评估眼前节参数。
方法:纳入57例接受无缝合SFIOL植入患者的60只眼和52例接受RPIOL植入患者的57只眼。前房深度(ACD),前房角(ACA),前房容积(ACV),前后角膜散光,使用Scheimpflug角膜地形图(PentacamHR,德国)。
结果:无缝合SFIOL组和RPIOL组术后UCVA和BCVA无统计学差异(分别为p=0.236,p=0.293)。两组患者术后眼压差异无统计学意义(p=0.223),两组IOP均有统计学意义的下降(p<0.001).虽然无缝合SFIOL组和RPIOL组在球形值(p=0.441)和球形等效性(p=0.237)方面没有统计学差异,圆柱值差异有统计学意义(p<0.001)。虽然前散光有统计学差异(p<0.001),后散光无统计学差异(p=0.405)。在ACV方面没有统计学差异,ACD,无缝合SFIOL和RPIOL组之间的ACA(分别为p=0.812,p=0.770,p=0.401)。
结论:在这项研究中,尽管无缝线SFIOL组和RPIOL组之间的柱度值和角膜前散光有统计学差异,视力没有受到影响。根据这项研究,无缝线SFIOL和RPIOL是两种在视力方面成功的方法,前段,白内障超声乳化术后无晶状体患者的角膜曲率测量结果。
OBJECTIVE: Evaluation of anterior segment parameters using the Scheimpflug corneal topography 1 year after surgery in patients who underwent sutureless scleral fixation intraocular lens (SFIOL) implantation using the modified Yamane technique and retropupillary iris-claw intraocular lens (RPIOL) implantation.
METHODS: A total of 60 eyes from 57 patients who underwent sutureless SFIOL implantation and 57 eyes from 52 patients who underwent RPIOL implantation were included. Anterior chamber depth (ACD), anterior chamber angle (ACA), anterior chamber volume (ACV), anterior-posterior corneal astigmatism, and keratometric values were assessed using the Scheimpflug corneal topography (Pentacam HR, Germany).
RESULTS: There was no statistically significant difference in postoperative UCVA and BCVA between the sutureless SFIOL and the RPIOL group (p = 0.236, p = 0.293, respectively). While there was no statistically significant difference in postoperative IOP between the two groups (p = 0.223), a statistically significant decrease in IOP was observed in both groups (p < 0.001). While there was no statistical difference between the sutureless SFIOL group and the RPIOL group in terms of spherical value (p = 0.441) and spherical equivalence (p = 0.237), there was a statistically significant difference in cylindrical value (p < 0.001). While there was a statistical difference in anterior astigmatism (p < 0.001), there was no statistical difference in posterior astigmatism (p = 0.405). There was no statistical difference in terms of ACV, ACD, and ACA between the sutureless SFIOL and the RPIOL group (p = 0.812, p = 0.770, p = 0.401, respectively).
CONCLUSIONS: In this study, although there was a statistical difference in cylindrical value and anterior corneal astigmatism between the sutureless SFIOL and RPIOL groups, vision was not affected. According to this study, sutureless SFIOL and RPIOL are two successful methods in terms of visual acuity, anterior segment, and keratometry outcomes in aphakic patients after phacoemulsification.
