Article Synopsis
- This study details 5 patients (10 eyes) who experienced corneal ectasia after undergoing cosmetic keratopigmentation (KTP) using a femtosecond laser.
- The research observed progressive changes in corneal shape and vision over 6 months to 4 years post-surgery, despite all patients initially having normal corneal conditions.
- The findings highlight that corneal ectasia can occur as a complication of KTP, emphasizing the need for thorough preoperative evaluations and patient education on avoiding eye rubbing to mitigate risks.
An increasing number of people are seeking elective cosmetic change of eye color. We review the surgical techniques, outcomes and complications arising from the various existing surgical alternatives, including cosmetic iris implants-which based on the available evidence should be considered malpractice-as well as laser iris depigmentation and cosmetic keratopigmentation. Laser iris depigmentation has been used clinically for aesthetic purposes without receiving official approval or licensing.

Methods: A prospective, interventional, consecutive, multicenter, series of cases of cosmetic KTP was included in the study. Forty consecutive patients underwent KTPs with mineral micronized pigments using a femtosecond laser-assisted intrastromal or superficial technique.
Purpose: To assess visual and refractive outcomes of toric iris-claw phakic intraocular lens (IOL) implantation in patients who had previously undergone deep anterior lamellar keratoplasty (DALK).
Methods: Retrospective case series including 24 eyes of 24 patients implanted with toric Artiflex or Artisan (Ophtec BV, Groningen, Holland) phakic IOL following DALK for keratoconus. During a 12-month follow-up, the main outcome measures were uncorrected and corrected distance visual acuities (UDVA and CDVA), refractive error components, topographic parameters, and endothelial cell count.
Purpose: To report the outcomes of a new model of epidescemetic keratoprosthesis (Kpro) implanted without total corneal trephination.
Methods: Patients were considered for implantation with the new Kpro model (KeraKlear) if they were at high risk of failure with standard penetrating keratoplasty (PK) or showed conditions with a poor prognosis following PK such as severe chemical injury. We used femtosecond laser to create the surgical planes adequate for the purpose of the Kpro implantation, and the Kpro was implanted intralamellar in 11 eyes and epidescemetical in 4 eyes.
Aims: To investigate the visual and refractive outcomes, safety, efficacy and stability of cataract surgery in eyes with stable keratoconus.
Methods: 17 eyes (10 patients) diagnosed as stable keratoconus, aged from 34 to 73 years (56.63 ± 12.
Purpose: To report a pupil-supported, iris-clip intraocular lens (IOL) that was explanted more than 28 years after implantation.
Methods: A pupil-supported, iris-clip, Sputnik-like IOL was implanted in the left eye of a 33-year-old man to correct aphakia after extracapsular cataract extraction due to trauma.
Results: Twenty-eight years after implantation, the patient was referred to our center with loss of vision.
Purpose: To evaluate the long-term outcomes of excimer laser myopic photorefractive keratectomy (PRK) for myopia higher than -6 diopters (D).
Design: A long-term (10-year) follow-up retrospective, interventional case series.
Methods: The study included 267 eyes of 191 patients with myopia with spherical equivalent (SE) of more than -6 D treated with myopic PRK at the Instituto Oftalmológico de Alicante, Alicante, Spain, using the VISX 20/20 excimer laser (Santa Clara, California, USA).
Purpose: To evaluate the long-term outcomes of excimer laser myopic photorefractive keratectomy (PRK) for myopia of less than -6 diopters (D).
Design: Long-term (10-year) follow-up retrospective, interventional case series.
Methods: The study included 225 eyes of 138 myopic patients with spherical equivalent (SE) between 0 and -6 D treated with myopic PRK at the Instituto Oftalmológico de Alicante, Alicante, Spain, using the VISX 20/20 excimer laser (Santa Clara, California, USA).
