Annually, well more than one million Americans have refractive surgery to correct their vision. Refractive surgery is any type of surgery that alters the refractive power of the eye. Lasik is the most well known of the procedures, but others are available, including Lasek, PRK, and Epi-Lasik. Most of the refractive surgeries rely on laser, but Conductive Keratoplasty (CK) uses radio wave energy.
Unfortunately, as common as the procedures have become, preventable injuries do occur. Most of the injuries can be divided into five major categories:
- Contraindications for surgery
- Surgeon error
- Failure to treat postoperative complications in a timely and proper manner
- Failure to obtain informed consent
- Equipment malfunction
Contraindications for Refractive Surgery
Some patients are poor candidates for refractive surgery. Eye diseases, such as keratoconus, corneal dystropies, or retinal detachments, are the most common contraindications for these patients.
A surgeon is supposed to evaluate the patient prior to surgery. A policy statement from the American Academy of Ophthalmology (AA0) explains the reasoning for the surgeon evaluation:
“The best interest of the preoperative patient is served by preoperative evaluation by the operating surgeon. Ethical and qualify of care standards are met only if the individual patient’s needs are addressed…. It is the ophthalmologist’s responsibility to provide quality control, prospectively, in the preoperative assessment.”
Unfortunately, the preoperative evaluation by the surgeon is not always done. This increases the chances that contraindications are missed. The consequences of performing surgery with contraindications can be extremely severe, including the need for corneal transplants.
Other reasons for negative surgical outcomes include poor skills of technicians responsible for reading measurements and surgeons taking unnecessary chances.
Surgeon Error
The surgeon’s inadequate technique or skills may result in poor alignment of the corneal flap or cutting into the cornea. In some instances, the wrong prescription is programmed into the laser.
