Presentation Transcript

Slide1:

Uses for Corneal topography: Refractive surgery Keratoconus Post surgery astigmatism Surgical planning for various disorders. Maintained by Visual Aids Centre Owner: Vipin Buckshey

Slide2:

Refractive surgery Used to screen candidates for normal corneal shape, patterns and ruling out suspicious or keratoconic patterns. Post operatively , topography can help to assess the dioptric change created at corneal level ( thus the effective change in the cornea). Topography can help for ruling out decentred or incomplete ablation Topography can help to post excimer ectasia or other changes. Maintained by Visual Aids Centre Owner: Vipin Buckshey

Slide3:

Keratoconus Early screening of keratoconus suspects is one of the most useful roles of topography . Early keratoconus and suspects look normal on slit lamp examination ,and the central keratometry (3 mm) gives only a limited assessment. Topography has become the gold standard in screening keratoconus suspects . The role of topography is paramount for monitoring progression and doing a timely collagen cross linking , and in contact lens fitting. Maintained by Visual Aids Centre Owner: Vipin Buckshey

Slide4:

Post surgery astigmatism It can be used for post cataract surgery and post keratoplasty corneal astigmatism can also be studied with the topographer . It can be used for selective suture removal or other interventions can be planned. Maintained by Visual Aids Centre Owner: Vipin Buckshey

Slide5:

Surgical planning: Limbal relaxing incisions and other methods of topography guided incision placement are used by surgeons to reduce post operative astigmatism . Disorders such as pterygium , limbal dermoid , localised corneal scars can cause a change in the corneal topography and thus the monitoring is very useful. Contact lens fitting , incision placement and intrastromal ring placement in keratoconus , monitoring of ocular vs corneal wavefront. Maintained by Visual Aids Centre Owner: Vipin Buckshey
