Purpose All neophyte contact lens wearers require training on how to handle contact lenses. Currently, almost no published information exists describing the most common approaches used by those involved in such training in soft contact lens wearers. This study aimed to gather information on the approaches taken by those conducting this training worldwide. Methods An online survey was created in English

Prospective assessment of corneal biomechanical properties and intraocular pressure after scleral lens wear: A 12-month follow-up study Cont. Lens Anterior Eye (IF 3.2) Pub Date : 2023-10-18 Rute J. Macedo-de-Araújo, Rita Maria Seco, José M. González-Méijome
Purpose To investigate the long-term influence of scleral lens (SL) wear on corneal biomechanical properties and intraocular pressure (IOP) in irregular and regular corneas. Secondary goal comprised evaluate the fluid reservoir (FR) thickness overtime and correlate it with the changes in corneal biomechanical parameters and IOP. Methods Seventy (70) eyes with irregular corneas (IC Group) and 21 eyes

Characterization of the external limbus on corneoscleral topography with ultrawide-field optical coherence tomography Cont. Lens Anterior Eye (IF 3.2) Pub Date : 2023-10-11 Clara Llorens-Quintana, Yan Li, Siyu Chen, James G. Fujimoto, David Huang
Purpose To present a new method for 3-dimensional external limbal demarcation on corneoscleral topography derived from optical coherence tomography (OCT). Limbal shape is investigated and compared to other landmarks. Methods Images from the anterior segment were obtained with a ultrawide-field (20 mm) OCT. An automated algorithm was developed to demarcate the topographic limbus based on the transition
