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.
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).
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).
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.
使用 Scheimpflug 角膜地形图评估改良 Yamane 技术行无缝线巩膜固定眼内透镜（SFIOL）植入术后 1 年和经后房虹膜夹型眼内透镜（RPIOL）植入术后患者的眼前节参数。
纳入 60 只眼（57 例）行无缝线 SFIOL 植入和 57 只眼（52 例）行 RPIOL 植入患者。使用 Scheimpflug 角膜地形图（德国 Pentacam HR）评估前房深度（ACD）、前房角（ACA）、前房容积（ACV）、前后角膜散光和角膜曲率计值。
无缝线 SFIOL 组和 RPIOL 组术后最佳矫正视力（UCVA）和最佳裸眼视力（BCVA）差异无统计学意义（分别为 p=0.236、p=0.293）。两组术后眼压差异无统计学意义（p=0.223），但两组眼压均显著下降（p<0.001）。无缝线 SFIOL 组和 RPIOL 组在球镜值（p=0.441）和球镜等效值（p=0.237）方面差异无统计学意义，在柱镜值（p<0.001）方面差异有统计学意义。前角膜散光差异有统计学意义（p<0.001），后角膜散光差异无统计学意义（p=0.405）。无缝线 SFIOL 组和 RPIOL 组在 ACV、ACD 和 ACA 方面差异无统计学意义（分别为 p=0.812、p=0.770、p=0.401）。
本研究中，无缝线 SFIOL 和 RPIOL 组在柱镜值和前角膜散光方面存在统计学差异，但视力未受影响。根据本研究，无缝线 SFIOL 和 RPIOL 是超声乳化白内障吸除术后无晶状体患者在视力、眼前节和角膜曲率计方面两种成功的方法。
