To compare visual performance and visual quality outcomes after phacoemulsification with two different clear corneal incision (CCI) distances anterior to the limbus in senile cataract patients.
Retrospective case series. Patients who had undergone phacoemulsification were divided into two groups according to the CCI distances anterior to the limbus. The CCI distances in group A range from 1 mm to 1.5 mm, while those in group B range from 0.5 mm to 1 mm. The visual acuity, refraction, surgically induced astigmatism (SIA), corneal aberrations, anterior segment parameters, and subjective vision quality were evaluated.
This study enrolled 54 eyes, with 27 eyes per group. Both groups had significant improvement in postoperative uncorrected visual acuity (UCVA) and corrected distance visual acuity (CDVA) ( < 0.05). There were no statistically significant between-group differences in postoperative UDVA, CDVA, SIA, corneal aberrations, anterior segment parameters, or VF-QOL questionnaire performance ( > 0.05).
The phacoemulsification with CCI distances ranging from 0.5 mm to 1.5 mm is an effective and safe therapy to senile cataract. The CCI distance anterior to the limbus that ranges from 0.5 mm to 1.5 mm is recommended for routine phacoemulsification.
比较老年白内障患者行超声乳化白内障吸除术时,两种不同的角膜缘前透明角膜切口(CCI)距离术后的视觉性能和视觉质量结果。
回顾性病例系列研究。根据角膜缘前CCI距离将接受超声乳化白内障吸除术的患者分为两组。A组的CCI距离为1毫米至1.5毫米,而B组的CCI距离为0.5毫米至1毫米。评估视力、屈光、手术源性散光(SIA)、角膜像差、眼前节参数和主观视觉质量。
本研究纳入54只眼,每组27只眼。两组术后裸眼视力(UCVA)和矫正远视力(CDVA)均有显著改善(P<0.05)。术后UCVA、CDVA、SIA、角膜像差、眼前节参数或VF-QOL问卷表现方面,组间差异无统计学意义(P>0.05)。
角膜缘前CCI距离为0.5毫米至1.5毫米的超声乳化白内障吸除术是治疗老年白内障的一种有效且安全的方法。建议在常规超声乳化白内障吸除术中采用角膜缘前0.5毫米至1.5毫米的CCI距离。
