Purpose This paper briefly reviews current explanations for corneal transparency and uses a well-developed model to try to explain the increased light scattering either accompanying corneal swelling or following phototherapeutic keratectomy (PTK). (cardiff.ac.uk)
In this report, we describe a case of corneal ectasia after photorefractive keratectomy in a patient who presented a suspicious tomography pattern preoperatively but had no degenerative alterations associated with pathologic keratoconus, as revealed by in vivo corneal confocal microscopy.

Excimer1
5 Recently, several authors have reported the use of excimer phototherapeutic keratectomy (PTK) for this condition. (bmj.com)
Superficial1
More active intervention with a bandage contact lens, epithelial debridement, 1 superficial keratectomy with a diamond burr, 2 anterior stromal puncture, 3 and Nd:YAG laser 4 have been used with varying success. (bmj.com)
We also review eligible case reports of post-photorefractive keratectomy ectasia to find similar characteristics. (bvsalud.org)
Recurrent2
Phototherapeutic keratectomy in recurrent epithelial erosions is a promising treatment, especially in recalcitrant cases with the erosion over the entrance pupil. (nih.gov)
Results: Over a 5 year period (October 1995 to October 2000) 76 eyes were treated for recurrent erosion syndrome with phototherapeutic keratectomy. (bmj.com)

Patients1
We compared the contrast sensitivity of GCD2 patients before and after phototherapeutic keratectomy (PTK) to evaluate the perioperative visual function in these patients. (jkos.org)

Lamellar Keratoplasty2
Combined procedures such as phototherapeutic keratectomy, anterior lamellar keratoplasty (automated lamellar therapeutic and deep lamellar),and posterior lamellar keratoplasty (Descemet-stripping automated endothelial keratoplasty and Descemet membrane endothelial keratoplasty triple), and phacoemulsification will be elucidated. (ascrs.org)
With FD-OCT, we can measure the depth of the stromal trough to decide the best treatment option: phototherapeutic keratectomy (PTK) or anterior lamellar keratoplasty. (crstodayeurope.com)
Stromal1
Additionally, the effect of topical Fe2O3 nanoparticles (NPs) (50 ng/ml) on corneal stromal wound healing following phototherapeutic keratectomy (PTK) was determined. (nih.gov)

Laser technology1
This is because an expert surgeon can manage most complications, as long as they have advanced diagnostic equipment such as the Artemis Insight 100 Insight VHF digital ultrasound scanner and high resolution OCT (optical coherence tomography), and the repair tool technology: phototherapeutic keratectomy (PTK) technology and topography-guided laser technology.
