Abstract Details


To study the outcomes of photorefractive keratectomy (PRK) in correction of refractive power with reduction of corneal opacity in a case of corneal scar with pseudophakia with irregulal pupil.


Cornea and refractive surgery services, Indira Gandhi Eye Hospital and Research Centre, Lucknow, India.


A 40 years old female presented with a history of corneal tear with secondary infection with traumatic cataract in her left eye and was operated for the same about 10 years back. Her left eye UDVA was 20/200 and CDVA was 20/60 with refraction of +3.00 DS/-2.50 DC@90. Sim Ks were 45.41 D@116 and 44.95 D@26. Minimum corneal thickness (MCT) was 487μm. Maximum scar thickness was 420μm. A topography guided customized PRK was planned with full correction of spherical and half correction of cylindrical powers.


Ocular examinations, refraction, topography and pacymetry were done at 1,3 and 6,12,18 and 24 months postoperatively. The eye has achieved UDVA of 20/30 at 3 months follow-up and the studied parameters remained stable thereafter.


PRK for corneal scar with pseudophakia is effective in cases of corneal opacity in which minimum corneal thickness (MCT) is appropriate, maximum scar thickness is away from visual axis and there is no ectasia. There was reduction in corneal scar size and thickness during ablation for refractive correction by PRK which explains the improvement of vision better than preoperative CDVA.
