Slowing of myopia progression by spectacles with highly aspherical lenslets—A narrative review

Optometry and Vision Science, Volume 103, Issue 9, September 2026.
ABSTRACT Purpose A new generation of myopia control spectacles has emerged, including spectacle lenses with highly aspherical lenslet technology (HAL lenses). To date, HAL lenses have only been thoroughly evaluated in a single site randomized clinical trial in China and a recently published, multicenter, North American clinical trial.

Short-term corneal changes with gas-permeable contact lens wear in keratoconus subjects: A comparison of two fitting approaches

Journal of Optometry, 2015
Purpose: To evaluate changes in anterior corneal topography and higher-order aberrations (HOA) after 14-days of rigid gas-permeable (RGP) contact lens (CL) wear in keratoconus subjects comparing two different fitting approaches.

Evaluation of interface quality in organ-cultured lamellar corneal transplants [PDF]

, 2012
Background: With increasing numbers of lamellar keratoplasties, eye banks are challenged to deliver precut lamellar donor tissue. In Europe, the most common technique of corneal storage is organ culture which requires a deswelling process before surgical

Keratometry and the Central Radius with Aspheric Corneal Surfaces

Current Eye Research
To develop a simple concept for deriving the central corneal radius (RC) from the keratometry (K) or simulated keratometry (SimK) radius (RS) and corneal asphericity (QC), and to show the differences RC-RS based on a large dataset of measurements from a modern anterior segment tomographer.Comparing the local slopes of surface representations with a ...

Analysis of Corneal Asphericity according to Age and Gender

The Korean Journal of Vision Science, 2020
Purpose : The purpose of this study was to investigate the distribution of corneal asphericity of all ages in Koreans and changes in corneal asphericity according to age and gender. Methods : A total of 317 people(317 eyes) were analyzed retrospectively. The refractive error was analyzed by the autorefractometer.

Epithelium-Off vs. transepithelial corneal collagen crosslinking in progressive keratoconus: 3 years of follow-up [PDF]

, 2020
Purpose To compare the efficacy of epithelium-off corneal collagen crosslinking (CXL) with transepithelial CXL in patients with progressive keratoconus with a follow-up of 3 years, taking into account the patients’ age and the location of the corneal ...
