Changes in vaulting of myopic and toric implantable collamer lenses in different lighting conditions.

Purpose: To evaluate the changes in vaulting of myopic and toric Implantable Collamer Lenses (ICLs) in different lighting conditions.

Methods: Thirty-seven eyes of 37 patients implanted with a myopic ICL and 26 eyes of 26 patients implanted with a toric ICL were examined using Visante optical coherence tomography (OCT) in photopic (257 lux) and mesopic (2 lux) conditions. Pupil diameter and distance changes between the ICL and adjacent intraocular structures were measured.

Vaulting of myopic and toric Implantable Collamer Lenses during accommodation measured with Visante optical coherence tomography.

Purpose: To study changes in vaulting of myopic and toric Implantable Collamer Lenses (ICLs) version 4 during accommodation with Visante optical coherence tomography (OCT), and analyze the relationship between vaulting and anterior subcapsular opacification.

Design: Cross-sectional study.

Participants: Seventy-seven eyes of 77 myopic patients were examined after implantation with an ICL (48 myopic, 29 toric).

[Optic neuritis--diagnosis, treatment and follow up].

A national group of neurologists and ophthalmologists have evaluated guidelines and recommendations for diagnosis, treatment and follow up of optic neuritis based on clinical experience and a review of relevant literature. Optic neuritis is a common, well characterised condition that appears as an isolated syndrome or as a manifestation of multiple sclerosis. Several other diseases must be considered for a differential diagnosis.
