Purpose: To evaluate the effectiveness of sequential custom phototherapeutic keratectomy (SCTK) for granular corneal dystrophy type 1 (GCD1).
Methods: Thirty-seven eyes of 21 patients with GCD1 were treated with SCTK to remove superficial opacifications, regularize the corneal surface, and decrease optical aberrations. SCTK is a sequence of custom therapeutic excimer laser keratectomies with step-by-step intraoperative corneal topography monitoring of results.
Purpose: To investigate if symptomatic conjunctivitis during the recovery phase of the disease could be associated to a persistent presence of SARS-CoV-2 in the upper respiratory tract. Secondary end points were to analyze the presence of SARS-CoV-2 in the conjunctiva of ocular symptomatic patients and to record the presence of ocular disturbances at this point of the disease.
Methods: An observational study including consecutive COVID19 patients treated at Humanitas Clinical and Research Hospital who were attending for nasopharyngeal swab to confirm the resolution of SARS-CoV-2 infection and end of isolation.
Purpose: Spreading from China, COVID-19 pandemic reached Italy, the first massively involved western nation. At the beginning of March, 2020 in Northern Italy a complete lockdown of activities was imposed. Access to all healthcare providers, was halted for patients with elective problems.

The SPT algorithm is a laser pulse technology software aimed at reducing surface irregularity of the stromal bed at the end of treatment.
Background: Change in lesion volume over time, measured on brain magnetic resonance imaging (MRI) scans, is an important outcome measure for natural history studies and clinical trials in multiple sclerosis (MS).

Methods: A total of 76 consecutive patients, diagnosed with PMH (41 eyes) or LMH (35 eyes) were included. Eyes with VPA were alternatively assigned to the surgical or control group.
Purpose: To report a case of bilateral, ring-shaped, intrastromal corneal opacities after corneal cross-linking (CXL) for progressive keratoconus.
Methods: A 21-year-old man with bilateral, progressive keratoconus underwent CXL with riboflavin 0.1% and ultraviolet A (UVA) light in the right eye and, 6 months later, in the left eye.

J Cataract Refract Surg
January 2005
Purpose: To evaluate the results of custom laser-assisted subepithelial keratectomy (LASEK) with a specially designed transition zone and smoothing for the treatment of refractive errors.
Setting: Department of Ophthalmology, Istituto Clinico Humanitas, Rozzano-Milan, Italy.
Methods: This prospective study involved myopic eyes having refractive surgery with the butterfly LASEK technique and the Nidek EC-5000 excimer laser.
Purpose: Treatment of highly aberrated eyes with opacities or irregularities consequent to previous refractive treatment, ulcers, keratitis, trauma, or corneal dystrophies remains a challenge for refractive surgeons. We evaluated the results of custom phototherapeutic keratectomy (CPK) with intraoperative corneal topography-based aberrometry and custom ablation in highly aberrated eyes.
Methods: We prospectively evaluated eyes undergoing custom phototherapeutic keratectomy (CPK) with custom ablation for corneal opacities and/or irregularities due to previous refractive treatment, keratitis, trauma, or dystrophies.
Purpose: Phototherapeutic keratectomy is a safe and effective treatment for many superficial diseases of the cornea. We applied intraoperative, epithelium-free, topography-based corneal aberrometry as a basis for custom phototherapeutic keratectomy (CPK) in highly aberrated eyes with opacities or irregularities consequent to previous refractive treatment, ulcers, keratitis, trauma or corneal dystrophies.
Methods: We evaluated eyes undergoing CPK for corneal opacities and or irregularities due to previous refractive treatment, keratitis, trauma, or corneal dystrophies, and treated 52 eyes of 50 patients.
Purpose: To evaluate long-term results of custom laser epithelial keratomileusis (LASEK) for correction of myopia and hyperopia using the Custom Ablation Transition Zone (CATz) software and hyaluronic acid masking fluid (Laservis) for final corneal smoothing.
Methods: We conducted a prospective study of 297 eyes of 167 patients. All eyes had LASEK for correction of myopia or hyperopia.
Purpose: To determine corneal aberrometric values in a normal population.
Methods: Corneal topography from a group of 4340 patients was retrospectively evaluated. Exclusion criteria were applied in order to select a population with good visual acuity, no previous ocular surgery, no contact lens influence, and no corneal disease.
