목적: 미세각막절개 양손 수정체유화술 후 말아서 삽입한 ThinOptX의 임상성적을 알아보고자 한다. 대상과 방법: 2005년 7월부터 2006년 5월 사이에 수술 받은 30명 34안에 대해 시력, 굴절력, 각막내피세포밀도, 눈부심 및 대비감도, 후낭혼탁 및 합병증에 대하여 조사하였다. 결과: 수술 전 환자들의 최대교정시력은 LogMAR시력으로 0.43±0.24이었고 수술 후 6개월째 0.04±0.09이었으나, 12개월째 0.14±0.12로 감소하였다. 각막내피세포밀도는 수술 전 2562±347.90 (cells/mm2)에서 수술 후 12개월째 2241±294.88 (cells/mm2)로 평균 13% 감소하였다. 수술 후 6개월째 측정한 대비감도는 명조건(photopic condition) 및 박명조건(mesopic condition)에서 증가된 결과를 보였고 눈부심은 모든 안에서 발생하는 것으로 관찰되었다. Grade 2 이상의 후낭혼탁은 6개월까지 29% 12개월까지 52%에서 발생하였다. 결론: 미세각막절개 양손 수정체유화술 후 ThinOptX의 삽입은 술 후 좋은 초기시력을 보였지만 인공수정체의 디자인과 관련하여 눈부심 및 후낭혼탁이 문제점으로 파악되어 이에 대한 추가적인 보완이 필요할 것으로 생각된다.

Purpose: To retrospectively evaluate the clinical results of insertion of a hydrophilic acrylic plate posterior chamber intraocular lens (ThinOptX) after bimanual microincision phacoemulsification. Methods: Thirty-four eyes of 30 patients who underwent bimanual phacoemulsification and ThinOptX implantation through a 2.0 mm incision between July 2004 and May 2006 were followed-up for more than 12 months. We examined best corrected visual acuity (BCVA), refractive errors, corneal endothelial cell density, halo and contrast sensitivity, posterior capsule opacification (PCO), and intraoperative and postoperative complications. Results: The preoperative mean logMAR BCVA was 0.43±0.24, and the postoperative BCVA was 0.04±0.09 after 6 months and 0.14±0.12 after 12 months. The preoperative corneal endothelial cell density was 2562±347.90 cells/mm2, and decreased to 2241±294.88 (cells/mm2) at 12 months postoperative. Postoperative contrast sensitivity at 6 months was increased in both photopic and mesopic condition. Halo was noted in all examined eyes. A PCO of 29% was evaluated at 6 months postoperative and a PCO of 52% was evaluated at 12 months postoperative. Conclusions: Bimanual phacoemulsification and ThinOptX implantation through a 2.0 mm incision resulted in good initial visual outcome and correction of refractive errors. However, problems such as halo and PCO associated with IOL design were noted. Therefore, further evaluation and correction of the IOL are needed.
