Abstract
Implantable Collamer Lenses (ICL) are phakic lenses that are implanted in the posterior chamber of the eye for the correction
of myopia, hyperopia, and astigmatism in those patients who cannot undergo corneal refractive surgery, the main feature of the
latest models. of ICL is a hole in the optical center of the lens, which facilitates the natural flow of aqueous humor. Among the
contraindications for ICL implantation are: Corneal pathologies, cataracts, glaucoma, retinal pathologies such as degenerations
or detachments, diabetic retinopathy, patients allergic to collagen, pseudoexfoliative syndrome, pigment dispersion syndrome,
pupillary abnormalities, endothelial count less than 2000 mm2, uveitis, under 20 years of age or with unstable refraction.
We present the case of a 24-year-old female patient who came to the clinic for refractive surgery due to high myopia, an ICL
18.00 D implant was proposed in the left eye. In the preoperative examinations: the UBM presented an iris plateau with multiple
angle-closing cysts. In the optic nerve OCT she presents a moderate and severe decrease in nerve fibers and the visual field with
PHG: outside normal limits, MD: -12.84 dB. After the postoperative period, the patient presented with ocular hypertension that
was controlled with antihypertensives, he achieved IOP control a month after the operation, but after a few months
postoperatively he presented a low endothelial cell count and an anterior subcapsular cataract, for which it was decided to
explant the ICL. Finally, cataract surgery was performed and a monofocal IOL was implanted.
