Some surgeons also believe that the stromal bed should be at least half of the original corneal thickness. 5 The disadvantage of this method is the lack of pre-operative information (i.e., prior to LASIK treatment). Sugar A, Rapuano C.J., Culbertson W. W., Huang D.,Varley G. A., Agapitos P.J, de Luise V.P., Koch D.D. PTA was still a more significant factor than the variables that comprise it., Some eyes dont fit the model. WebFor example, pre-treatment refractive power, as well as thickness and curvature changes following corneal incisions, are used to perform post-operative calculation of the total corneal refractive power (TCRP) after LASIK treatment.

If there are other tools or resources you would like us to consider, please let us know. LASIK experts in Los Angeles like Doctor Moosa say that LASIK is known for treating varying levels of farsightedness, nearsightedness, and astigmatism. DipCompSci(Cantab); Tariq A. Lewis, MSci, ARCS, OMT; Marine Gobbe, MSTOptom, PhD; Johnny Moore, FRCOphth, PhD, MD; Tara Moore, BSc, PhD Long-term Visual and Refractive Outcomes After Is there a history of other risk factors, such as eye rubbing? Thus, percent tissue altered is derived from (FT + AD) CCT. Results will be sent to you without interpretation. LASIK involves creating a corneal flap using a microkeratome (Figure 1) or a femtosecond laser, reshaping the cornea using an excimer laser to remove tissue from the underlying stromal bed and then replacing the flap.
