Abstract Details

Purpose:

To report a case of a high myopic patient with aphakia and no capsular support where a phakic foldable iris claw intraocular lens (IOL) was introduced retropupillary.

Setting:

Hospital de Santa Maria- North Lisbon Hospital Center

Methods:

A 72 years old male patient, with ophthalmic history of high myopia, left eye (OS) cataract surgery 12 years ago and right eye (OD) phtisis bulbi due to total retinal detachment. Came to our department complaining of OS decreased visual acuity (VA). OS best corrected visual acuity (BCVA) was 10/200. OS biomicroscopy revealed the IOL- capsular bag complex subluxated in vitreous cavity. Three port 23-gauge vitrectomy was performed, followed by dislocated IOL explantation through a 3,2 mm corneal incision. Explanted IOL was -7,00 diopters. Implantation of a phakic foldable iris claw IOL retropupillary was then performed.

Results:

Through the same corneal incision, a foldable iris claw IOL was inserted in the anterior chamber with the concave surface positioned anteriorly. For IOL fixation, the shown technique was adapted from that used for retropupillary implantation of PMMA iris claw aphakia IOLs. Due to the flexible consistency of the polysiloxane IOL body, the fixation forceps was positioned near the rigid PMMA haptics for better grasping. After 10 months of follow-up, visual acuity improvement with low surgical induced astigmatism was achieved (BCVA: 40/200). The IOL is stable, with normal intraocular pressure and good cosmetic results.

Conclusions:

Retropupillary foldable iris claw IOL implantation proved to be an effective and safe procedure for the correction of high myopic aphakic eyes. The main advantage being the associated small corneal incision and low surgical induced astigmatism.
