LASIK, or Laser-Assisted In Situ Keratomileusis, is a surgical procedure designed to correct common vision problems, such as nearsightedness, farsightedness, and astigmatism. The surgery reshapes the cornea—the front surface of the eye—to improve visual acuity. Despite the popularity and widespread adoption of this procedure, it is not without potential complications, some of which may arise immediately after the procedure or several years later.
Dr. Boshnick has developed a specialized approach to addressing these complications using scleral lenses. These large, gas permeable lenses are designed to vault over the compromised cornea, touching only the white part of the eye, or the sclera. The space between the back surface of the scleral lens and the front surface of the cornea is filled with a sterile saline solution, creating a continually moist environment for the cornea. This process assists in promoting comfort and fostering a healing environment for the cornea.
These scleral lenses are designed using computer technology to ensure a precise fit, and they effectively replace the distorted, compromised cornea as an optical surface, essentially providing a new, smooth refractive surface for the eye without additional surgery.
Through this innovative use of scleral lenses, Dr. Boshnick is able to address many of the complications arising from LASIK surgery, enhancing patients’ visual acuity and comfort, and fostering corneal health and recovery.
Common complications after LASIK surgery can include dry eyes, induced astigmatism, issues with the LASIK flap, loss of vision which cannot be corrected with eyeglasses or contact lenses, visual aberrations like halos and glare, post-LASIK corneal ectasia, and epithelial ingrowth.
Scleral lenses are specially designed to vault over the compromised cornea without touching it, instead resting on the white part of the eye (sclera). The space between the lens and the cornea is filled with sterile saline solution, providing a continually moist environment that promotes healing and offers comfort, while the lens itself replaces the distorted cornea as an optical surface.
Post-LASIK corneal ectasia is a rare but serious condition in which the cornea thins and bulges outward, leading to distorted vision. This can occur months or even years after LASIK surgery. Scleral lenses, which vault over the cornea and replace it as an optical surface, can provide an effective non-invasive solution for this complication.
The saline solution in scleral lenses maintains a moist environment for the front surface of the eye, which is crucial for promoting the healing of the compromised corneal tissue, and also offers comfort to the patient.
Yes, in fact, scleral lenses are often a good solution for those experiencing chronic dry eyes after LASIK. The saline solution between the lens and the cornea provides a continually moist environment that can alleviate dry eye symptoms.
The healing process can vary significantly among individuals depending on the severity of the corneal damage and other individual health factors. Regular follow-up appointments with the eye care provider will be necessary to monitor the healing process.
Yes, the design of scleral lenses allows them to replace the distorted, compromised cornea as an optical surface, helping to correct issues like halos, glare, and double vision caused by LASIK complications.
