The PRK procedure was performed by first marking an area of 9 mm diameter on the anterior corneal surface and debriding the epithelium with an axe blade, followed by laser application with the AMARIS excimer laser (SCHWIND eye-tech-solutions GmbH&Co.
In the PRK group, preoperative and 6 months postoperative CRF values were 10.
With high corrections, the stromal wound healing after
PRK can lead to haze formation in high percentage of cases.
The FDA recently approved two laser systems as safe and effective for performing
PRK on adult patients with mild to moderate nearsightedness and mild astigmatism.
Durrieet al 1 have described three wound healing types which can be helpful in following the
PRK patients post-operatively.
By the mid-1990s,
PRK - photorefractive keratectomy - had become an accepted method for fixing myopic eyes.
Dr Milne also outlined a very effective pain management regimen that, in his view, has virtually eliminated the pain issue associated with other surface ablation procedures, such as
PRK.
The procedure preserves the structural integrity of the stroma and is expected to minimize discomfort, shorten the length of visual recovery, and reduce the incidence of haze associated with other surface ablation procedures, such as
PRK and LASEK.
This entire process, Epi-LASIK, produces virtually instant visual results similar to LASIK but with the stable long-term visual outcomes of
PRK.
Epi-LASIK combines the best of today's most popular refractive surgeries, LASIK and
PRK, but does not require the surgeon to cut the patient's cornea or apply alcohol as is done in comparable procedures.
Buck performs refractive LASIK &
PRK along with comprehensive eye care including cataract, glaucoma, eyelid, eye muscle and diabetic laser surgery.
In addition to LASIK, the section includes detailed information on refractive procedures such as custom LASIK, LASEK,
PRK, LTK, CK, prescription inserts, and investigational procedures for presbyopia.
