“…Satisfactory results were also reported by Alió et al, 28,29 in 2 large prospective case series of highly aberrated corneas after refractive surgery treated with excimer ablations based on corneal wavefront topography. Despite this, the nature of TG ablations should always be taken into account and subjects should be informed that a second procedure to address the refractive error may be necessary.…”

“…Photorefractive keratectomy (PRK) with adjunctive Mitomycin C has been shown to be safe and effective with the use of the 193 nm excimer lasers. These lasers have been widely used in the past two decades and up to the present [2–4]. With the recent development and introduction of the 213 nm solid-state laser, use of this machine for refractive surgery has been increasing in various parts of the world.…”

Purpose. To evaluate the accuracy, efficacy, stability, and safety of photorefractive keratectomy (PRK) enhancement using the Pulzar 213 nm solid-state laser (SSL) with adjunctive Mitomycin C in eyes previously treated with laser assisted in situ keratomileusis (LASIK) with residual error of refraction. Methods. This is a prospective noncomparative case series of 16 eyes of 12 patients who underwent PRK for residual refractive error after primary LASIK. Mitomycin C 0.02% was used after the PRK to prevent haze formation. Outcomes measured were pre- and postoperative manifest refraction spherical equivalent (MRSE), uncorrected (UDVA) and best-corrected distance visual acuity (CDVA), and slit lamp evidence of corneal complications. Results. The mean UDVA improved from 20/70 preoperatively to 20/30 postoperatively. The average gain in lines for the UDVA was 2.38. After six months of followup, the postoperative MRSE within 0.50 D in 56% (9) of eyes and 94% (15) eyes were within 1.0 diopters of the intended correction. No eyes developed haze all throughout the study. Conclusion. PRK enhancement with adjunctive use of Mitomycin C for the correction of residual error of refraction after LASIK using the Pulzar 213 nm solid-state laser is an accurate, effective, and safe procedure.

“…Wavefront-guided ablation has been used to treat patients with high-order aberrations in refractive surgery. [9] We used wavefront-guided PRK to reduce surgically induced high-order aberrations and correct hyperopic shifts after PTK; vision, refraction, and corneal surface regularity showed significant improvement in this TBCD case. Simultaneous PRK and PTK have been used to treat high astigmatism alongside radial keratotomy and keratoplasty.…”

Phototherapeutic keratectomy (PTK) has been used to treat anterior corneal dystrophy but may cause hyperopic shift or corneal high-order aberration. We describe the successful treatment of a case of a 43-year-old female with Thiel–Behnke corneal dystrophy, using PTK followed by wavefront-guided photorefractive keratectomy (PRK). The patient had high corneal aberration and hyperopic shift after PTK in both eyes. The corneal surface regularity index and surface asymmetric index increased after PTK and decreased after wavefront-guided PRK. Vision improved from preoperative 20/400 and 20/60 to postoperative 20/20 and 20/25 in the right eye and the left eye, respectively. Additional wavefront-guided PRK may enhance the effects of PTK by reducing irregular corneal surfaces and by correcting PTK-induced hyperopic shift.
