Abstract Details

Purpose:

To evaluate the safety and effectiveness of implanting a foldable anterior chamber phakic iris claw intraocular lens in children with unilateral high myopia and anisometropia.

Setting:

Department of Ophthalmology Faculty of Medicine Cairo University

Methods:

Prospective interventional non-randomized case series Inclusion criteria: Children < 12 years Myopia > -7 D with or without astigmatism up to 2D Intolerance to glasses and contact lens Exclusion criteria: Abnormal topography AC depth (internal) <3 mm Endothelial cell count < 2800 cells/mm Number of eyes: 6 Follow up: 12 months Pre-operative evaluation: UCVA,BCVA ,manifest and cycloplejic refraction, Pentacam, Specular microscopy. Technique: Under general anaesthesia, implantation of Veriflex foldable phakic IOL (Advanced Medical Optics,USA) through 3.5mm incision, using cohesive viscoelastic and enclavation needle. Follow up : UCVA, BCVA, Centration Specular microscopy repeated at 3 and 12 months.

Results:

Mean age :7.9+1.7(SD) years Mean UCVA improved from 0.033+0.0074(SD) (decimal) to 0.47+0.16(SD) 12 months after surgery (P<0.05) Mean BCVA improved from 0.37+0.12(SD) to 0.58+0.09(SD) at 12 months (P<0.05) Spherical equivalent improved from -9.44+1.27(SD) to -0.48=0.29(SD) at 12 months (P<0.05) No significant intra- or postoperative complications were encountered Endothelal cell count showed a reduction by 8.7% at 3 months with minimal change afterwards(1.2%) at 12 months

Conclusions:

Implantation of foldable iris claw anterior chamber phakic IOL appears to be safe and effective in children with unilateral high myopia. The significant improvement in postoperative visual acuity is probably due to image magnification and suggests an important role in the management of amblyopia.
