Intacs After Laser in situ Keratomileusis: A Preliminary Report
Purpose:
To assess the corneal topographic and refractive results and feasibility of placing Intacs in eyes with a history of previous laser in situ keratomileusis (LASIK) surgery.
Methods:
This was a prospective study on 25 eyes with residual myopia between -0.75 and -3.00 D. Residual myopia in these patients was secondary to regression or planned undercorrection due to preoperative thin corneas.
Results:
Main outcome measures included uncorrected visual acuity, preservation of best spectacle-corrected visual acuity, refractive predictability, corneal topographic changes, and evaluation of surgical complications.
Conclusions:
Initial Intacs procedures after previous LASIK were performed uneventfully. In addition to correcting residual myopia, these procedures may improve night vision symptoms in some patients. These cases may improve our understanding of the ideal corneal shape. [J Refract Surg 2000;1 6(suppl):S236-S238].
