PURPOSE: To report the outcomes of posterior-assisted levitation (PAL) to retrieve nuclear fragments and subluxated intraocular lenses (IOLs).
SETTING: Singapore National Eye Centre, Singapore, Singapore.
METHODS: In a retrospective series, the case notes of consecutive surgeries performed by a single surgeon between 1999 and 2006 were reviewed. Posterior-assisted levitation was performed for intraoperative posterior capsule rupture with nucleus-IOL dislocation or for late subluxation of posterior chamber intraocular lenses (PC IOLs). This was accomplished by the pars plana insertion of a needle followed by levitation of the subluxated object. Ophthalmic viscosurgical device injection was not used as an adjunct for levitation.
RESULTS: Fourteen patients with PAL were followed for a mean of 18.71 months (range 1 to 79 months). There were 3 cases of dropped nucleus/nuclear fragments, 1 case of intraoperative subluxated PC IOL, and 10 cases of late subluxated PC IOLs. Complications included 1 case of retinal detachment occurring 20 months after PAL and 1 case of cystoid macular edema in a patient with previous anterior uveitis. Best corrected visual acuity was 20/40 or better in all except 3 patients (1 retinal detachment, 1 corneal edema/scarring, 1 unspecified).
CONCLUSION: Posterior-assisted levitation provided an effective, relatively noninvasive means of levitating nuclear fragments and PC IOLs with few complications.
