LASIK surgeons know about the long term issues of LASIK and other corneal refractive surgical procedures, but this information is not disclosed to patients.
Corneal refractive surgery alters the shape and thickness of the cornea. The altered corneal surface causes the measurement of intraocular pressure (IOP) to be inaccurate. This measurement is critical in the diagnosis of glaucoma. Patients who have had LASIK may lose vision due to undiagnosed glaucoma.
Everyone will develop cataracts, including patients who have had LASIK and other forms of refractive surgery. Cataract surgery involves removal of the natural lens inside the eye and implantation of an artifical intraocular lens (IOL). The altered corneal shape after LASIK results in inaccurate power calculation of the implant. This means that LASIK patients' vision will be out of focus after cataract surgery.
