Two-panel clinical figure showing a 42-year-old patient with keratoconus previously treated with intracorneal ring segment implantation and photorefractive keratectomy, followed by anterior chamber iris-fixated phakic intraocular lens implantation for residual ametropia. Panel A shows anterior segment OCT demonstrating the intracorneal ring segment within the corneal tunnel and the anterior chamber configuration. Panel B shows a slit-lamp photograph demonstrating a well-fixated iris-claw intraocular lens and a quiet anterior segment. — A 42-year-old male with keratoconus previously treated with intracorneal ring segment (ICRS) implantation and photorefractive keratectomy (PRK) for corneal remodeling, who subsequently underwent anterior chamber iris-fixated intraocular lens (artisan) implantation for residual ametropia. Postoperatively, uncorrected distance visual acuity (UDVA) reached 0.90 and improved to a corrected distance visual acuity (CDVA) of 1.0 with minimal residual astigmatism, while intraocular pressure remained within normal limits. (A) Anterior segment OCT showing the ICRS positioned within the corneal tunnel and a stable anterior chamber configuration with a well-fixated iris-claw intraocular lens. (B) Slit-lamp photograph confirming appropriate iris fixation of the intraocular lens and a quiet anterior segment without signs of inflammation.
