Refractive Surgery

Calgary, Alberta

Who is a good PRK candidate?

PRK and LASIK both use the excimer laser to reshape the cornea to eliminate the need for glasses and/or contact lenses. Patients over the age of 44 will likely need to wear glasses for close work such as reading, fine hobbies such as sewing, or close activities like putting on make-up.

PRK (photorefractive keratectomy) can correct refractive error even if you are not a good candidate. Because there are no incisions and no corneal flap, the procedure is available to more people and poses less risk of complication. Some people may prefer PRK due to lifestyle or occupational factors. At Western Laser Eye Associates in Calgary, Alberta Canada, the professional, highly trained PRK team will explain which refractive surgery is best suited to your vision needs.

Basic qualifications

There are some basic requirements that all refractive surgery candidates should meet including:

• Eyes should be fully developed (typically 18 years old or older)
• You should have stable vision for at least one year prior to surgery
• You understand the risks involved with PRK surgery and have realistic expectations

Refractive surgery is not appropriate if you are pregnant or nursing. Hormonal changes can change refractive error, minimizing or reversing the effectiveness of the surgery. Also, if you have a family history of keratoconus you may not be a good candidate for corneal refractive surgery.

PRK when you cannot have LASIK

There are many circumstances that can make LASIK inappropriate but are fine for PRK. PRK does not involve the creation of a corneal flap, making it a safer option for some people including those who have:

• Thin corneas
• Corneal dystrophy
• Recurrent corneal erosion
• Corneal scars from trauma or infection
• Large pupils
• Eye conditions

Eye conditions such as glaucoma are sometimes discovered during the refractive examination and consultation. After doing a thorough dilated eye examination, Dr. Anderson Penno will explain whether or not she has identified any eye conditions as well as what procedure is recommended for your individual case. If an eye condition is found that disqualifies you from surgery, Dr. Anderson Penno will explain why surgery may not be an option and what furthers steps may be recommended.

Lifestyle and occupation

PRK may be the preferred choice for people whose occupations or lifestyle choices do not allow for safe LASIK including:

• Athletes
• Anyone who engages in contact sports
• Pilots
• Police officers
• Military personnel
