- What is photorefractive keratectomy (PRK)? Photorefractive keratectomy (PRK) is a procedure used to reduce the need for corrective eyewear by reshaping the cornea of the eye with a laser, thereby changing the way the eye focuses light. An excimer laser is used to ablate (remove) a thin layer of the cornea, changing the cornea's refractive (focusing) power.

- Photorefractive Keratectomy (PRK) and LASEK. A lucrative business for ophthalmologists, PRK is a harmful, unnecessary eye surgery. PRK preceded LASIK, but then fell out of favor as LASIK was introduced. From the ophthalmologist-businessman's perspective, LASIK did not require as much chair time as PRK, and LASIK was more marketable than PRK.

What is Creatine Kinase Blood Test Creatine kinase also known as CPK or Creatine phosphokinase is an enzyme that is found in the brain, heart, and skeletal muscles. This enzyme encourages a particular biochemical reaction to occur. CK normally adds phosphate to creatine present in our body and turns it into molecule phosphocreatine which is high-energy.

Diabetic retinopathy Panretinal photocoagulation, or PRP (also called scatter laser treatment), is used to treat proliferative diabetic retinopathy (PDR). The goal is to create 1,600 - 2,000 burns in the retina with the hope of reducing the retina's oxygen demand, and hence the possibility of ischemia. It is done in multiple sittings.

Creatine Phosphokinase (CPK) Test: Facts & Information Creatine kinase (CK), also known as creatine phosphokinase (CPK) or phospho-creatine kinase, is an enzyme (EC 2.7.3.2) expressed by various tissues and cell types. CK catalyses the conversion of creatine and consumes adenosine triphosphate (ATP) to create phosphocreatine (PCr) and adenosine diphosphate (ADP).

PRK: Feeling Better and Healing Faster Find an Ophthalmologist. This article is from September 2008 and may contain outdated material. Since photorefractive keratectomy was approved by the FDA in 1995, patient outcomes have steadily improved. The Achilles’ heel of PRK, however, remains the time required for epithelial healing. It can take a week to recover an intact epithelium and several weeks before best-corrected acuity is achieved.

- PRK Eye Surgery Procedure — What is Photorefractive Keratectomy. PRK laser eye surgery, or Pho­tore­frac­tive Ker­a­te­c­to­my is part of a fam­i­ly of pro­ce­dures called “sur­face abla­tions” because the laser is applied direct­ly on the sur­face of the cornea rather than under a flap, as with LASIK. The PRK surgery is done under top­i­cal anes­the­sia and takes about 5 min­utes per eye.

What does it mean to have a high CPK reading? CPK is the abbreviation for a blood test called creatine phosphokinase. CPK is an enzyme found primarily in muscles. This includes the muscles in the heart. Any muscle injury or damage can cause a rise in the blood level of CPK. For example, a person would likely have a high CPK after a fall. A high CPK also occurs when someone has a heart attack.

PRK Laser Eye Surgery: What Is PRK And How Does It Differ From LASIK? PRK (photorefractive keratectomy) is a type of refractive surgery to correct myopia (nearsightedness), hyperopia (farsightedness) and astigmatism. PRK was the first type of laser eye surgery for vision correction and is the predecessor to the popular LASIK procedure. Though PRK recovery takes a bit longer than recovery from LASIK eye surgery, PRK is still commonly performed and offers advantages over LASIK for some patients.
