Abstract Details


To report the use of phototherapeutic keratectomy (PTK) with mitomycin-C (MMC) to treat adenoviral corneal infiltrates without causing refractive shift.


Maya Ophthalmology Center, Ankara, Turkey


Patients without significant refractive error with subepithelial infiltrates were treated with PTK and MMC 0.002% for 1 minute with a target of emmetropia by making simultaneous hyperopic ablation to the peripheral corneal zone and myopic ablation to the central corneal zone. The uncorrected visual acuity (UCVA) , presence of photophobia, refractive error, corneal topography, anterior segment optical coherence tomography (OCT) were evaluated before and after surgery.


Our study included 4 eyes of 4 patients. The follow up time was from 4 to 6 months. After the treatment photophobia and corneal opacities were significantly decreased, all the patients had improved UCVA and also there wasn't any significant refractive shift.


Modified PTK , may be an effective technique for the treatment of corneal adenoviral opacities without causing significant refractive shift and for providing visual rehabilitation.
