Assessment of eye for Further surgery after LASIK
Rasha Hassan Abdu Ismail;
Abstract
LASIK and PRK are accurate and considerably safe methods to correct refractive errors. Laser surgical methods are continuously undergoing refinement, which may improve the accuracy and safety of the procedures.
Refractive surgery will be seen not as a single procedure for a single problem, but rather as a set of refractive procedures to treat the overall vision requirements of a particular patient.
Human ivCM studies have shown, however, that neural recovery is still incomplete after several years postoperatively, and furthermore, that the decrease of anterior stromal and LASIK flap keratocyte density exceeds that of normal aging. These findings warrant special attention on the long term corneal integrity, and especially, on occasions of other ocular operations or re-operations.
Lasik and other forms of laser refractive surgery (i.e. PRK, LASEK and Epi-LASIK) change the dynamics of the cornea. These changes make it difficult for ophthalmologist to accurately measure your intraocular pressure, essential in glaucoma screening and treatment. The changes also affect the calculations used to select the correct intraocular lens implant in cataract surgery.
Until a direct, user-friendly, and precise method of calculating corneal power after excimer laser surgery becomes available, we have to become familiar with the formulas described previously. This task is not easy, as the number of options increases year after year.
The correct intraocular pressure and intraocular lens power can be calculated if there is preoperative, operative and postoperative eye measurements.
LASIK induced corneal polarization axis shift affects peri-papillary RNFL measurements customized compensation for corneal polarimetric changes after LASIK allows the normalization of several thickness parameters, with the exception of average RNFL thickness and the discriminating parameter NFI, which should be critically considered during the follow up of patients who underwent LASIK for ametropia correction.
