title: Suture fixation of an intraocular lens combined with pars plana vitrectomy and gas tamponade.
abstract: We describe suturing an intraocular lens (IOL) after pars plana lensectomy and vitrectomy combined with gas tamponade in 4 patients with vitreoretinal disease and subluxated lenses that could not be managed with capsular tension rings. The IOL haptics were sutured before the fluid-gas exchange in a horizontal (case 1), oblique (cases 2 and 4), and vertical (case 3) manner. In a case of unavoidable horizontal fixation due to limited scleral space, the upper part of the IOL tilted anteriorly postoperatively because of the enhanced effect of the gas bubble. A peripheral anterior iris synechia also occurred. The IOL remained well positioned in cases with oblique and vertical fixations, and no other complications occurred. Careful preoperative planning of the surgical design can help avoid unnecessary horizontal fixation.
