Evidence on scleral contact lenses and intraocular pressure [PDF]

, 2017
It has been hypothesised that scleral contact lens wear may potentially elevate intraocular pressure (IOP) as a result of post-lens fluid forces exacerbated by eyelid tension, or ocular versions that alter the lens fit and result in corneal bearing or ...

Contact Lens Fitting in Keratoconus

Delhi Journal of Ophthalmology, 2010
Keratoconus is a progressive, non-inflammatory, asymmetric ectatic corneal disorder that results in high amount of myopia and astigmatic refractive error. Early cases may be managed by spectacles; however, the definitive management is use of contact lens.
