Outstanding Results Using the Femtosecond Laser for Keratoconus Treatment
TLC Yonge Eglinton Laser Eye Centre uses the femtosecond laser for keratoconus treatment, providing patients in Toronto, ON, with ultimate in state-of-the-art care. Our surgeons employ this high-tech surgical laser to place corneal ring inserts and in other treatments for keratoconus patients.
About Keratoconus Treatment and the Femtosecond Laser
Keratoconus, which causes distortion of the cornea, effects more than one in 2,000 patients. The disease can cause eye irritation and a number of serious visual problems, which may not be correctable with glasses or contacts. Keratoconus surgical treatments include corneal ring inserts (implants), cross linking, laser reshaping, and corneal transplant.
Donor corneal transplants can replace a diseased cornea with a healthy one, but the procedure comes with a lengthy recovery period and potential post-surgical risks. Our other surgical techniques are minimally invasive and offer quick recoveries. Cross linking can strengthen the cornea to halt the progression of keratoconus, while corneal rings work by flattening the distended cornea to correct myopia and astigmatism.
Many eye surgery procedures are more effectively performed with the advanced, computerized femtosecond laser, which allows for ultra-precise cuts with optimal preservation of surrounding tissue. This infrared laser creates short light pulses without generating heat, and uses remarkable speed: a femtosecond is equivalent to a trillion seconds.
For patients who require a corneal transplant, our surgeons use the femtosecond laser to create precise incisions to match donor tissue with the patient’s eye.
TLC Laser Applications for Keratoconus
For insertion of corneal rings, minuscule tunnels must be created between the layers of corneal tissue. These tunnels are individually tailored to suit precisely measured specifications and the thickness of a patient's selected corneal ring. The femtosecond laser is ideal for this procedure, allowing our doctors to realize increased placement accuracy without damage to the cornea.
With this laser, energy can be concentrated at a precisely defined depth within the cornea, the dome-shaped outer layer of the eye. Tissue is evaporated in minute measurements, expanding and separating to create tiny tunnels to accommodate crescent-shaped implants. A natural sterilizer, the laser also reduces risk of post-procedure infection.
In the cross-linking process, the epithelial, or outer surface of the cornea, is precisely removed with the laser in order to treat the eye with liquid riboflavin and ultra-violet light.
We also use the laser for reshaping of the cornea, reducing peaks and irregularities in the surface to improve vision. Precise mapping of the cornea ensures this computerized laser treatment is fully customized. The process can make wearing contact lenses more comfortable or reduce the need to wear them. Used in conjunction with cross linking, the degenerating cornea can be stabilized, and the laser changes locked into place.
For patients who require a corneal transplant, our surgeons use the femtosecond laser to create precise incisions to match donor tissue with the patient’s eye. The laser promotes faster healing after this procedure, and leaves a stronger, more stable cornea to minimize future risks.
