Abstract

Purpose: To compare the postoperative clinical outcomes after cataract surgery and implantation using the BunnyLens $MF^{(R)}$ and $ReSTOR^{(R)}$ multifocal intraocular lenses. Methods: Sixty-five eyes implanted with multifocal intraocular lenses were divided into two groups involving either $ReSTOR^{(R)}$ (39 eyes) or BunnyLens $MF^{(R)}$ (26 eyes) lenses. In these two groups, the distant and near visual acuity, astigmatism, spherical equivalent, and contrast sensitivity test were examined at preoperative and postoperative 1 week, 8 weeks, and 24 weeks. We compared the clinical efficacy between the two groups before and after cataract surgery using statistical analysis. Results: The mean value of distant and near visual acuity, and spherical equivalent of both groups after intraocular lens implantation were significantly improved, compared with the preoperative values (p < 0.05), while there was no significant differences between the two groups (p > 0.05). The means of postoperative distant and near visual acuity, astigmatism, and contrast sensitivity test were not significantly different between $ReSTOR^{(R)}$ and BunnyLens $MF^{(R)}$ lenses (p > 0.05). The mean numeric error of spherical equivalent at the final postoperative 24 weeks was $-0.17{\pm}0.50$ diopters (D) for the $ReSTOR^{(R)}$ lenses and $-0.34{\pm}0.52D$ for the BunnyLens $MF^{(R)}$ lenses (p > 0.05). Conclusions: BunnyLens $MF^{(R)}$ and $ReSTOR^{(R)}$ lenses showed no significant difference in clinical efficacy, including distance and near vision, spherical equivalent error, and contrast sensitivity test after cataract surgery. However, it should be noted that BunnyLens $MF^{(R)}$ lenses had a tendency toward myopic shift compared with $ReSTOR^{(R)}$ lenses.

목적: 백내장수술 후 다초점인공수정체인 BunnyLens $MF^{(R)}$를 삽입한 환자의 수술 전과 수술 후 근거리 및 원거리에서의 시력교정에 관한 임상적 유용성을 알아보고자 하였다. 대상과 방법: 백내장으로 진단을 받고 다초점인공수정체 삽입술을 시행한 환자 중에서 $ReSTOR^{(R)}$를 삽입한 39안을 대조군, BunnyLens $MF^{(R)}$를 삽입한 26안을 실험군으로 분류하여, 총 65안을 분석하였다. 수술 전과 수술 후 1주째, 8주째, 24주째의 원거리 및 근거리 시력과 난시, 구면렌즈대응치, 대비감도를 비교하고, 두 군 간의 수술 후 임상적 유용성을 비교하였다. 결과: 두 군 모두에서 술 전에 비해 술 후 원거리 및 근거리 시력, 구면렌즈대응치가 유의하게 향상되었으나(p<0.05), 두 군 간의 유의한 차이는 없었다(p>0.05). 수술 후 원거리 및 근거리 평균 시력과 난시, 대비감도는 대조군과 실험군은 두 군 간 유의한 차이가 없었다(p>0.05). 구면렌즈대응치의 평균실제오차는 $ReSTOR^{(R)}$와 BunnyLens $MF^{(R)}$는 수술 24주째, 각각 $-0.17{\pm}0.50D$, $-0.34{\pm}0.52D$였고 유의한 차이가 없었다(p>0.05). 결론: 백내장수술 후에 삽입되는 다초점인공수정체인 BunnyLens $MF^{(R)}$는 원거리 및 근거리 시력에서 $ReSTOR^{(R)}$와 유의한 차이가 없었고, 정시안을 기준으로 통계적으로 유의하지는 않으나, $ReSTOR^{(R)}$에 비해 BunnyLens $MF^{(R)}$가 근시의 경향을 보였다.
