Re-fixation of a previously implanted intraocular lens using the Yamane technique

Refixation of a previously implanted intraocular lens using the Yamane technique Refixation of a previously implanted intraocular lens (IOL) using the Yamane technique.

The patient had previously undergone implantation of a three-piece IOL; however, the lens became displaced and decentered. The patient complained of poor vision; despite a recent surgery, there was no improvement, prompting him to seek a consultation.

Visual acuity: 2/20 in the right eye; 16/20 in the left eye.

Intraocular pressure: 12/13 mmHg.

Eye position: Physiologically normal; full range of motion without restriction. Scleral vessels: Unremarkable. Sclera white; no tenderness.

Anterior segment: Cornea clear, smooth, and lustrous; no opacities detected. Anterior chamber of moderate depth; aqueous humor clear; subatrophic iris; pseudophakia; IOL position decentered (inferior to the visual axis).

Fundus: Pale pink fundus reflex. Optic disc pale pink with distinct margins; vascular bundle visualized centrally; artery-to-vein ratio 2:3.

Visual fields: Full.

Admission diagnosis: IOL dislocation (right eye), pseudophakia (right eye). Clinical diagnosis: IOL dislocation (right eye), pseudophakia (right eye).

Repeat surgery on the right eye recommended.

Following the examination, I scheduled IOL repositioning using the Yamane technique. During the procedure, it was found that one haptic was positioned correctly, while the other was not. I decided to transect the malpositioned haptic and secure it in the proper position.

Postoperative status: Satisfactory. The eye is quiet; mixed scleral injection is present. Iris subatrophy is noted. Pupil size is 6 mm; the artificial lens is visible within the pupillary area. The IOL is centrally positioned.

One-week follow-up: Satisfactory condition with positive progress. The eye is quiet; mixed scleral injection is present. Iris subatrophy is noted. Pupil size is 6 mm; the artificial lens is visible within the pupillary area. The IOL is centrally positioned.

Visual acuity in the right eye was 14/20; intraocular pressure was 12.6/13.1.
