A true excessively flat soft contact lens (or soft contact lens skirt as is the case in this hybrid lens) may have too much material to rest all of its surface touching the conjunctiva. The extra or excess material can "flute" up causing a wrinkle at the edge of the lens and/or a bubble.
The importance of the edge profile in fitting soft contact lenses: …
Apr 16, 2021 · The edge design of soft contact lenses is often overseen during contact lens fitting or during followup visits. By means of illustrations of different edge profiles and a review of the literature on this topic, the attention of contact lens practitioner should …
Characterization of Soft Contact Lens Edge Fitting during Daily …
May 13, 2018 · In the present study, we aimed at evaluating the conjunctival response to soft contact lens which was characterized as an overlap of conjunctival tissue at the edge of the lens and the presence of the peripheral PoLTF during the daily wear.
Impact of Soft Contact Lens Edge Design and Midperipheral Lens …
Dynamic OCT coupled with high-resolution video demonstrated that soft contact lens movement and image-corrected ocular surface indentation were influenced by both lens edge design and midperipheral lens shape profiles.
Characterization of Soft Contact Lens Edge Fitting Using Ultra …
The present study demonstrates the feasibility using OCT to characterize the edge fitting of soft contact lenses and paves the way to study the relationship between lens fitting and ocular responses. In vitro simulation clearly predicted the mismatch points between the …
(PDF) Impact of Soft Contact Lens Edge Design and Midperipheral Lens …
Aug 13, 2013 · Purpose: To evaluate the influence of soft contact lens midperipheral shape profile and edge design on the apparent epithelial thickness and indentation of the ocular surface with lens...
Optical Assessment of Soft Contact Lens Edge-Thickness
Aug 7, 2022 · To assess the edge shape of soft contact lenses using Gabor-Domain Optical Coherence Microscopy (GD-OCM) with a 2 μm imaging resolution in three dimensions, and to generate edge-thickness profiles at different distances from the edge tip of soft contact lenses.
Similarly, the lens should also show no edge standof (fluting), which would lead to discomfort. The lens should remain approximately central to the cornea in all positions of gaze. Failure to achieve this may result in episodes of corneal desiccation and mechanical stress on the peripheral cornea.
Effect of soft contact lens edge design and mid peripheral shape …
Dec 1, 2013 · Purpose: To evaluate the influence of soft contact lens edge design and mid-peripheral shape profile on lens movement, epithelial thickness and ocular surface indentation.
[PDF] Impact of soft contact lens edge design and midperipheral lens …
Sep 11, 2013 · Dynamic OCT coupled with high-resolution video demonstrated that soft contact lens movement and image-corrected ocular surface indentation were influenced by both lens edge design and midperipheral lens shape profiles.
