PRK over LASIK with HAZE

This is a photo of a cornea that underwent LASIK surgery followed by PRK surgery. Note the haze in the center of the cornea. The vision with this eye is reduced even though this patient is able to wear a scleral lens which is providing her with 20/40 vision without distortions. The haze is permanent.

Patient who Traveled to Canada for PRK has Permanent Haze. Previously 20/20, now 20/30 with Haze

This is a photo of the left eye of a patient who went to Canada to have PRK done on this eye. This patient was told that there is a laser being used for PRK in Canada that is not yet approved by the FDA in the United States. This photo was taken about 1 year after the PRK was done. Look carefully at the cornea directly over the pupil. Note the grey- white haze. This is permanent and has reduced the best corrected visual acuity in this eye by 2 lines. In other words, before undergoing PRK this eye was correctable to 20/20. Now the best corrected visual acuity in this eye is 20/30. Of course the quality of the vision in this eye, even though it is 20/30 is not the same as it once was. One of the complications encountered with PRK is corneal haze.

Five Eyes with Permanent Haze from PRK

Below are photos of 5 different eyes that underwent photo refractive keratotomy or PRK. Look carefully and note the cloud or haze in the center of the cornea opposite to the line of sight. This haze is permanent and is caused by an inflammatory reaction within the cornea from the laser. The cloudy corneas seen here have reduced the visual acuity in these patients' eyes. The risk of irreparable corneal damage from PRK is real regardless if it is "topography guided" or not. Also know that US or FDA approval does not signify a stamp of approval or the elimination of any risk of ocular damage. I am providing you with impartial information and have no financial interest in whatever you decide to do. This is not true of your surgeon. The best way to address your issues with glare, starbursts and halos is with a well designed and fit scleral lens.

PRK in 2011 with Declining Vision. Now 20/20 with GVR Scleral Lens

This patient visited our office from Winnipeg, Manitoba. In 2011 he underwent photorefractive keratectomy (PRK) surgery. Almost immediately following this procedure he started losing quality vision. For over one year he was unable to drive a car because he did not feel safe. His vision in dim light and at night was worse. He told us that very often he was unable to recognize faces. As a result of his vision loss he became severely depressed. Contact lenses and eyeglasses were of little help. Last year he visited an internationally renown eye institution in the U.S. for help. The doctors there were not able to help him and he returned home. He returned to the doctors that performed the PRK who felt that his problem was in his head. They explained that the reason he was not seeing clearly was that his brain was not receiving the vision signals from his eyes properly. Finally, on one of his last visits to the surgeon who performed the PRK, the surgeon suggested that he get a girlfriend. We recently fit this patient with GVR Scleral lenses. With these lenses and a very small eyeglass prescription needed to be worn in conjunction with the GVR lenses, this patient was able to see 20/20 in each eye without distortions and in all lighting conditions with excellent comfort.

Declining Vision and Dry Eyes after PRK. Patient Seeing Clearly with GVR Scleral Lens

This patient visited our office from Italy where he underwent photo refractive keratectomy (PRK) eye surgery 8 years ago. This surgery was done to eliminate his myopia and astigmatism. Shortly after undergoing this surgery, he noticed his vision decreasing and his eyes becoming increasingly dry. He was unable to see clearly at distance or near and eyeglasses or contact lenses did little to provide relief. While he was able to function in bright daylight, he was unable to indoors and at night. In addition to the above vision issues he had painfully dry eyes and was addicted to a variety of eye drops. 3 years ago we examined this patient and provided him with GVR Scleral lenses. He is now able to see clearly both in daylight and at night. In addition, because these lenses do not touch his corneas but bath his dry corneas in a reservoir of unpreserved saline solution, he no longer suffers from dry eyes while wearing his lenses.

PRK Leads to Distorted Corneas and Bad Dim Light Vision. Now 20/20 in Both Eyes with GVR Scleral Lens

This photo shows on the left, our student extern Tina Cheung, our patient in the center and her brother on the right. Our patient and her brother recently traveled from Vancouver, British Columbia to visit our office. In 2006, she underwent photo refractive keratotomy surgery (PRK) in both eyes. This surgery left her with distorted corneas which has prevented her from functioning visually indoors and in dim lighting environments, especially at night. For the past 9 years she has not been able to drive at night. Over these years she visited 6 different eye doctors in her community who told her that they were not able to provide help. One doctor told her that the reason she could not see in low light situations was that she had cataracts (she does not). Finally out of desperation, this patient's brother insisted on flying her to Miami to visit our office for help. When she arrived here we fit her with GVR Scleral lenses which have allowed her to see clearly in daylight and in the evening clearly (20/20) in both eyes without any distortions such as glare and halos. In addition, she is able to wear her GVR lenses all day comfortably.

Blurred Vision, Burning Eyes: This Is a Lasik Success?

EyePrint Pro

EyePrintPro technology creates a scleral lens based on a mold of the cornea. The molding is accurate to 1 or 2 microns and fits perfectly because it exactly mirrors the irregularities of the individual corneal surface. The technology is well suited for post-Lasik, Keratoconus, RK, eye injury, and corneal transplant patients. Read More in this PDF about EyePrintPro Scleral Lens Technology
