1) 목적 : 토릭(난시교정) 다초점 인공수정체를 이용한 four-flanged 공막 내 고정술의 임상 결과 보고
2) 관찰 : 2.8mm 크기의 각막절개를 통한 4개 점을 이용한 무봉합 공막 고정술을 적용하여 인공수정체 삽입술을 한 환자들 중 완전하게 시력을 회복한 두 케이스를 설명하고자 한다.
첫 번째 경우, 봉합을 위한 4개의 구멍이 있는 2개의 햅틱 플레이트(plate-haptic) 디자인의 단초점 토릭(난시교정) 인공수정체를 5-0 폴리 프로필렌 모노필라멘트 봉합사를 이용하여 고정했다.
두 번째 경우, 첫 케이스와 동일한 햅틱 디자인의 이중초점 인공수정체를 고정시켰으며, 수술하는 동안 결막 또는 공막 봉합, 접착제, 플랩 형성은 필요하지 않았다. 수술과 관련된 합병증은 없었다.
3) 결론 및 중요성 : four-flanged 공막 내 고정술은 수술 후 시력의 예후가 기대되는 섬모체소대(섬모체와 수정체를 연결하는 인대)가 약한 환자들에게 도움이 될 수 있겠다.



To report clinical outcomes of a four-flanged intrascleral fixation technique using toric and multifocal intraocular lens.



We describe two cases of premium intraocular lens (IOL) implantation after which the patients fully recovered their visual function following a four-point sutureless scleral fixation technique via a 2.8-mm corneal incision. In the first case, a monofocal toric hydrophobic lens consisting of two haptic plates with four holes for suturing was fixated with 5–0 polypropylene monofilament. In the second case, a bifocal hydrophobic lens with the same haptic design was fixated. No conjunctival or scleral sutures, glue, or flap formation was required during the surgery. There were no complications related to the surgical process.


Conclusions and Importance

A four-flanged intrascleral fixation technique may benefit patients with poor zonular support who have high expectations for postoperative visual quality.
