| The exquisite precision of this ultraviolet laser could be harnessed to sculpt and recontour the corneal surface, a procedure termed as photorefractive keratectomy. |
|
| Implants would serve as a less permanent alternative to corrective surgical techniques such as radial keratotomy or photorefractive keratectomy. |
|
| With PRK, or photorefractive keratectomy, the surgeon cuts away at the surface of the cornea. |

|
| Several different types of polymer thin films demonstrate photorefractive properties. |
|
| Research into photorefractive polymers is very intense, mainly because these polymers can be used for holographic storage. |
|
| They have also been approved for photorefractive keratectomy, but only to treat certain degrees of nearsightedness and some forms of astigmatism. |
|
| These corneal sculpting techniques are known as photorefractive keratectomy and in situ keratomileusis. |
|
| Approved procedures include radial keratotomy, photorefractive keratectomy, laser-assisted in-situ keratomileusis and more recently, intra-corneal rings. |
|
| Photorefractive keratectomy evolved concurrently with the development of laser technology within refractive surgery. |
|
| Photorefractive keratectomy is similar to LASIK but does not involve use of a corneal incision or a flap. |
