Complications After LASIK Surgery

What To Do After Lasik Surgery?

LASIK eye surgery is a procedure to correct refractive errors. This method has become very popular across the globe, making it very accessible to all with a refractive eye problem. LASIK allows the eye to be free from contact lenses and eyeglasses for a very long time. In fact, millions of people in the US have undergone this procedure to correct their vision. However, there are also side effects or complications of this procedure that you need to know.


The common side effects of LASIK surgery include, haze, seeing halos around the eye, dry eyes and fluctuating vision. These side effects are expected to last for a few weeks, and in some cases for more than four month. However, some common side effects can trigger a more serious problem.

The complications of this procedure are a game changer. One might suffer from moderate to severe visual aberrations. Apart from the physical stress,  one has to address the emotional and psychological anxiety caused by the postoperative outcome.

What People Are Commonly Doing

Unfortunately, patients having suffered the complications of the eye procedure would seek another eye doctor to treat their condition.  Eyesight restoration after the LASIK surgery is not for every eye doctor to treat. It takes expert knowledge and skills to restore the damaged cornea caused by LASIK. Often patients will go back  for a LASIK touch-up or enhancement, but unfortunately this can increase the complications.

Expert Eye Doctor

What separates an eye doctor to another eye doctor is their expertise in the field. Second opinions, in this case, are necessary to put an end to one’s vision problem. The main goal here is to seek a treatment that can restore the eyes to its fullest.

There is hope for people with post LASIK complications. There are expert eye doctors who have the experience, invested in acquiring the most modern equipment, continue to advance their knowledge and skills to help those who are not completely free from post LASIK vision problems.

Where To Find The Experts

Hopping from one doctor to the other does not offer a guarantee of a complete treatment. What is vital here is for one to connect with a dependable eye doctor, that is known in the eye industry. A doctor who can help manage and treat the complications of post-LASIK successfully. The post LASIK management and treatment is often a non-surgical intervention with the use of (specialty) contact lenses, scleral lenses, PVR PROSE, EyePrint Pro, and other options. (soft lenses, RGP lenses, hybrids, scleral hybrids)

LASIK surgery is a modern way to correct the eye vision caused by a refractive error, and there are post-surgery complications that some people have suffered. Fortunately, these complications are treatable by doctors who specialize in the restoration of post refractive surgery.

PROSE Lenses – Pellucid Marginal Degeneration (PMD)

Pellucid Marginal Degeneration:

Pellucid Marginal Degeneration is a sub-category of Keratoconus. Pellucid corneas involve a larger distorted geographic area usually extending from the inferior corneal margins up to the center of the cornea. It is not unusual for 50% or more of the corneal surface to be involved. Because so much of the cornea can be affected, fitting this type of cornea can be challenging. The problem we face as eye care practitioners is fitting the steep areas if the cornea without adversely affecting the flatter areas.

PVR PROSE Lenses | GPVR PROSE Treatment:

PVR PROSE- Precision Vision Rehabilitation  Prosthetic Replacement of the Ocular Surface Ecosystem

Our PVR PROSE Treatment is a process that uses a prosthetic device, like a scleral lens, to replace the ocular surface to provide functional vision to complex corneal conditions. Utilizing our knowledge, experience, and technology, like the Vistante- Optical Coherence Tomography OCT, we are able to customize a prosthetic PROSE lens, with the precise measurements down to the micron. With an exact fit, there is proper movement, comfort, and perfect vision.

PROSE Lenses are large-diameter gas permeable contact lenses specially designed to vault the entire corneal surface and rest on the “white” of the eye (sclera). In doing so, PROSE scleral lenses functionally replace the irregular cornea with a perfectly smooth optical surface to correct vision problems caused by, keratoconus, Lasik failures, post-surgical complications, and other corneal irregularities.

Because PROSE Lenses / scleral lenses are designed to vault the corneal surface and rest on the less sensitive surface of the sclera, these lenses often are more comfortable for a person with corneal irregularities caused by keratoconus and other corneal irregularities A special liquid fills the space between the back surface of the lens and the front surface of the cornea. This liquid acts as a buffer and protects the compromised corneal tissue. Scleral lenses are designed to fit with little or no lens movement during blinks, making them more stable on the eye, compared with traditional corneal gas permeable lenses. These lenses are almost always very comfortable and the vision provided by them is extremely good. The great majority of patients are able to wear their scleral lenses almost all of their waking hours without problems.

Dr. Irwin Azman, Keratoconus Specialists in Maryland, prescribes PVR PROSE Lenses for a variety of hard-to-fit eyes, including patients with Stevens-Johnson Syndrome, Radial Keratotomy and Lasik Complications and Lasik failures, keratoconus, Corneal Ectasia, Post-Surgical Vision Loss, and Pellucid Marginal Degeneration.

Dr. Irwin Azman specializes in keratoconus, LASIK failures and other corneal irregularities neither avoids nor declines the challenge of prescribing the most difficult cases.
