DM : A relative contraindication. Lasik are likely to get epithelial defects. These defects and PRK healing likely slow.
HT : Avoid using phenylephrine for pupil dilation. Patients are more likely to have subconjunctival hemorrhage. This commonly resolves in a few weeks. If someone is on blood thinning agents or aspirin the tendency to bleed increases
Keloids: This is a tendency to form scars. The collagen in the skin and cornea are different. It was contraindicated with early lasers. LASIK is preferred. PRK has been performed. Mitomycin C use may be warranted.
Meditation meditation or the field of psychically immunobiology has someone advantages in refractive surgery. If the mind is, patients are more relaxed and our able to keep their eyes open in focus on the target. Postoperative Lee also students of meditation can tolerate better.
Enhancements. With the advent of blend zones the refinement of lasers and
Arthritis. Dry Eyes and autoimmune problems may lead to thinning.
Kidney Transplant. Discuss with the kidney doctor. Patient may be on immune suppressants, which are
Thyroid. Superficial Punctate Keratitis. Exophthalmoses or protrusion of the eyes may prevent lids covering the globe.
Glaucoma: RNFL loss may occur with high pressure of suction. This has never been conclusively proven. Full documentation prior to surgery including visual fields and RNFL
Amblyopia. A condition where the eye does not see 20/20. Patients with high hyperopia and astigmatism may improve their vision and see better than they have ever seen.
Lagophthalmos. Eye at risk of developing exposure keratitis.
Entropion. The lids are turned inward directing the lashes to the cornea
Trichiasis The eyelashes may rub on the cornea and cause epithelial defect. Therefore the offending lashes should be epilated prior to surgery.
Breast Implant or other surgery. Patients undergoing any other surgery should inform their anesthetists and doctors about having had LASIK. During anesthesia the eyes are likely to remain open causing exposure keratitis. The eyes should be instilled with lubricant ointment and meticulously taped shut.
Stabismus. Patient may prefer Monovision if the strabismus is not cosmetically a problem. This may stop the need off prisms or strabismus surgery. The strabismologist should be involved prior to the LASIK
Binocularity. Both the eyes must work together to retain binocularity. If the eyes are working separately for more than 3 months in adult life they may loose their binocularity permanently. Hence in cases of monovision its important that for a few hours a day both the eyes be made to work together, by wearing glasses
“I was so scared to have Lasik but so tired of contacts.The surgery itself was painless and now I see better than I did with contacts.”*
