Corneal evaluation of prospective aphakic wearers of contact lenses.
A recent investigation' has shown that the comea of the aphakic eye swells less than that of the normal fellow eye when fitted with identical hydrophilic lenses. This confirms previous clinical impressions and would suggest that a metabolic difference may exist between the corneas of the normal and the aphakic eye. The present investigation was therefore devised to assess certain aspects of the...
متن کاملExtended-wear aphakic soft contact lenses and corneal ulcers.
A review of 100 aphakic extended-wear soft contact lenses is presented for the period July 1980 to August 1981. Four previously successfully fitted patients with either American Optical Company's Sofcon or Cooper Laboratories' Permalens for extended wear developed corneal ulcers either directly under the lenses or shortly after removal. Three of the female patients were well controlled diabetic...
متن کاملCorneal Sensitivity and Contact Lenses.
IT is a matter of experience that certain persons adjust well to contact lenses while others do not, despite perfect fitting. This adjustment is greatly facilitated if the sensitivity of the cornea is decreased, as it is after cataract extraction. One is therefore tempted to consider corneal sensitivity as a determining factor for the success of a fitting. Previous investigation of the subject ...
متن کاملCorneal vascularisation and contact lenses.
EDITORIAL The cornea is avascular for the simple reason that to be otherwise would compromise its role as the primary refracting surface of the eye. As a result, situations that may cause vascularisation of this beautifully transparent tissue are energetically avoided. Visual disturbance caused by vascular encroachment upon the central cornea region is, perhaps, the most obvious threat. However...
متن کاملPredicting success with silicone-hydrogel contact lenses in new wearers.
PURPOSE to evaluate changes in tear metrics and ocular signs induced by six months of silicone-hydrogel contact lens wear and the difference in baseline characteristics between those who successfully continued in contact lens wear compared to those that did not. METHODS Non-invasive Keratograph, Tearscope and fluorescein tear break-up times (TBUTs), tear meniscus height, bulbar and limbal hyp...
