To report a case of corneal ectasia after unilateral excimer laser phototherapeutic keratectomy (PTK) in order to treat corneal scarring following recurrent pterygium surgery.
: Whipps Cross University Hospital, London, United Kingdom
Clinically significant iatrogenic keratectasia is a rare but well recognized complication following laser in situ keratomileusis, particularly in eyes with thinner corneas. In many instances this can markedly compromise visual outcome and hence is a cause for concern. However, iatrogenic keratectasia is less common after PTK.
We report a case of corneal ectasia over a period of 20 years following PTK for corneal scarring after recurrent pterygium surgery, which was evaluated using computerised cornea topography and pachymetry.
To the best of our knowledge, this would appear to be the first report of corneal ectasia over a period of 20 years after unilateral PTK for corneal scarring following recurrent pterygium surgery. FINANCIAL INTEREST: NONE
