How do RGPs improve visual optics? : They are able to fill the gaps and neutralise corneal irregularity. What is the first diagnostic clue to keratoconus? : Observations made during retinoscopy -Scissoring reflex -Charleux oil droplet sign How to do retinoscopy on a keratoconic patient? : Use any portion of the ret-reflex that seems to be more distinct/brighter and attempt to neutralise it. How to refract a keratconic patient? : -Use LARGE steps according to just noticeable difference...

What is the Secondary/intermediate curve? : The curve on the posterior side of the contact lense between the base curve and peripheral curve. Usually 0.7mm to 1.6mm flatter than the base curve radius. The width is affected by the OZ diameter and peripheral width. What is the peripheral curve? : The outermost curve on the posterior side of the contact lens. It clears the flatter periphery and prevents lens impingement in the limbal areas What measurements effect the size of the peripher...
