Purpose: To describe the main causes of explantation of phakic intraocular lenses (PIOLs) according to the anatomical site of implantation (angle supported, iris fixated, or posterior chamber).

Methods: This multicentric, retrospective, and consecutive study sponsored by the Spanish Ministry of Health comprised a total of 240 eyes (226 patients) explanted due to PIOL complications. Clinical data of 144 angle-supported lenses, 24 iris-fixated lenses, and 72 posterior chamber lenses explanted were recorded preoperatively and postoperatively.

Purpose: To describe the successful use of a double intrastromal tunnel femtosecond-assisted keratopigmentation technique to manage a case of unilateral Urrets-Zavalia syndrome.

Methods: A 33-year-old man was referred with a history of trauma in his right eye due to a labor-related accident. Because of myopic anisometropia, he had been previously implanted with an angle-supported phakic intraocular lens.

Unlabelled: We describe a new surgical technique of femtosecond-assisted keratopigmentation (KTP) in a 23-year-old woman with severe visual dysfunction secondary to unilateral essential iris atrophy due to the presence of iridocorneal endothelial syndrome in her left eye. The patient presented with complaints of photophobia and monocular diplopia in the affected eye. Femtosecond-assisted KTP surgery was performed in this eye.

Aim: To investigate the functional and cosmetic outcomes of keratopigmentation (KTP) in cases of moderate to severe visual dysfunctions owing to different iris disorders.

Methods: 11 eyes with moderate to severe visual disabilities related to iris defects underwent KTP for functional and cosmetic restoration using micronised mineral pigments and assisted with modern technologies such as femtosecond laser and new automated keratopigmentation instruments for the intrastromal and superficial application of the pigments.

Results: Following the KTP surgery, the visual-function-related symptoms improved in all cases, from significant improvement to total elimination.

Purpose: To evaluate and compare the clinical and confocal microscopic outcomes achieved with two different procedures for cross-linking (CXL) in eyes with keratoconus: CXL with epithelial debridement and CXL with intrastromal pocket.

Methods: This retrospective study included 27 eyes of 21 patients (age range: 18 to 53 years) diagnosed with keratoconus who underwent implantation of intracorneal ring segments and CXL with two different techniques: CXL with previous epithelial debridement (classic group, 16 eyes) and CXL with intrastromal pocket for riboflavin infusion (pocket group, 11 eyes). Visual, refractive, topographic, aberrometric, and pachymetric data were evaluated during 12-month follow-up.

Purpose: To evaluate the safety and efficacy during 5-year follow-up of phakic intraocular lens (PIOL) implantation to correct high anisometropia in amblyopic children who were non-compliant with traditional medical treatment including spectacles or contact lenses.

Methods: Retrospective study of 10 eyes of 10 children with high anisometropia who underwent PIOL implantation (9 with an iris-supported IOL and 1 with a posterior chamber IOL). Patient age at the time of implantation ranged from 2 to 15 years.
