Predictability of corneal flap thickness in laser in situ keratomileusis using a 200 kHz femtosecond laser

Abstract

This study provides evidence of the predictability and lower variability of LASIK flaps created using the femtosecond laser. Consecutive patients having LASIK had good, predictable, and stable outcomes at the 3-month mark.

Femtosecond laser refractive surgery

“…They found that the central cap thickness accuracy was -0.7 mm and reproducibility was 4.4 mm, with 96% of eyes within 10 mm of the intended. These two studies suggest that the predictability and consistency of cap construction in SMILE is comparable to FS-LASIK flap [13,14].…”

Demographics of patients having cataract surgery after laser in situ keratomileusis

“…Most recent studies [18][19][20][21][22][23][24][25][26] report the ratio of men having LASIK as 40% to 50%. Although the reasons for this discrepancy remain unclear, one possible explanation is that in the group of eyes with a long AL, including post-LASIK eyes, men tended to have cataract surgery more frequently than women, as shown in the results.…”

Relationship between Corneal Thickness and Radius to Body Height

“…Corneal thickness is an important anatomical characteristic of the anterior eye and a useful indicator of corneal health, 1 a specific indicator for corneal abnormalities 2 and an essential determinant for suitability of refractive surgery. 3 An analysis, however, of the literature reporting human corneal thickness over a 30-year period indicated that a wide range of values could be encountered for nominally healthy adults and, at best, values between 473 and 595 μm would be within normal limits. 1 While some of the differences between studies can be attributed to the use of different measuring devices or different underlying optical principles, 1,4 no substantial or consistent differences in central corneal thickness in adults appeared to exist for those of Caucasian origin when age, gender or refractive error were considered.…”
