Risks & Complications

Serious complications caused by malfunctioning of equipment

The precision flap-making instrument and excimer laser are always maintained according to the specifications of the manufacturer. Both equipments have emergency battery power supplies to complete the procedure if electricity is lost at any time. Despite this regular maintenance, the precision flap-making instrument or the excimer laser could malfunction, requiring the procedure to be stopped before completion that may lead to damage to cornea which ultimately results in loss of vision.

Assessment of eye health history

  • History of wearing glasses: It is important to determine if your vision has stabilized or is changing and history of previous eye injury.

  • History of contact lens wear: Contact lenses may change the shape of the cornea or act in such a way as to prevent the ophthalmologist from determining your correct prescription.

  • Most ophthalmologists require that soft contact lenses to be discontinued at least 3 days and rigid contact lenses 2 to 3 weeks prior to the evaluation.

  • History of ocular or systemic diseases and medications: Some eye diseases and medications can affect your suitability for performing laser eye surgery

Intra-operative complications of LASIK surgical procedure

A short flap occurs when the precision flap-making instrument cannot complete its movement. As a result, the flap becomes too small, leaving insufficient space for the laser treatment to be done. The flap is repositioned and the laser is not performed.

A free flap occurs when the flap becomes detached from the cornea. This complication is extremely rare with advanced technology. In order to ensure perfect alignment, once the laser treatment is complete, the surgeon marks the cornea before creating the flap.

Formation of unwanted debris around the flap and wrinkling of flaps

Infections caused in cornea due to complications in LASIK surgery

With any surgical procedure, infection of the cornea is possible. But severe infection, even if treated with antibiotics, lead to permanent scarring and loss of vision. Though the vast majority of our patients experience a significant improvement in their vision, we do not promise that the procedure will be completely effective or make your vision better than it was before the surgical procedure. If a slight possibility arise from the procedure would cause your vision to be blurred or other disturbances, including permanent loss of vision.
