To develop with a thin film interferometer new parameters to describe the drying properties of contact lenses; these are: time to first break-up (onset latency), duration of lens surface drying (drying duration), maximum speed of increase in the drying area (maximum speed), and the time to reach maximum drying speed (peak latency). These new parameters were compared with the contact angle (CA) measurement of contact lenses by the captive bubble (CB) technique
Purpose:To investigate the wetting of a soft contact lens (SCL) after storage in various multipurpose solutions (MPS) (compared to wetting with the pack solution), to assess the sustained benefits after 8 hours of wear.
In this second course in the contact lens series, hard (RGP) contact lens materials, hard contact lenses and their verification methods, fitting procedures of hard lenses, contact lenses for presbyopia, therapeutic and cosmetic contact lenses, will be taught over a ten week period covered with one lecture hour and two clinical and laboratory hours per week.
Here, review of thin lens optics, introduction to contact lenses, soft contact lens materials, soft contact lenses and their verification methods, fitting procedures of soft lenses, contact lens clinic procedures and policies, record keeping and follow-up care, will be taught over a ten week period covered with one lecture hour and two clinical and laboratory hours per week.
Ultrasonography, ocular electrophysiology diagnostic tests (ERG, VEP, EOG), tomographic and scanning laser polarimetry of the optic nerve head and nerve fibre layer will be covered over ten weeks with one lecture hour and four hours of clinical practice per week.
