Corneal stability after discontinued soft contact lens wear

Base curves of therapeutic lenses and their effects on post Epi-LASIK vision and pain: A prospective randomized clinical trial

“…Some studies suggest that soft lenses might experience a little warpage, but this is rarely the case with soft lenses. 25,26 Thus, the UCVA value is probably reliable when related to corneal wound healing after epi-LASIK, and wound healing at 4 days after epi-LASIK was apparently better with the 8.8-mm base curve lens than with the 8.4-mm base curve lens. One previous study reported the effect of the bandage contact lens base curve on epithelial healing after LASEK.…”

Assessment of anterior and posterior corneal indices using two Scheimpflug analyzers

“…Even within the same system, small decentrations in BFS can manifest as large deviations in peripheral elevation. The effects of contact lenses on corneal elevation and curvature have been eliminated from the equation because all subjects were advised to stop wearing soft contact lenses for at least 2 weeks (3) ; furthermore, all subjects that had worn rigid contact lenses in the past 6 months were excluded from the study. The images were obtained on the same day, thus decreasing any additional confounding factors.…”

“…undergone previous ocular surgeries, those with any systemic disease (including diabetes mellitus, connective tissue disease, hypertension, and collagen vascular diseases), and/or those who had worn rigid contact lenses in the past 6 months were excluded. Soft contact lens wearers were asked to discontinue wearing their contact lenses for at least 14 days prior to measurements (3) . The study received the approval of the Institutional Review Board of the American University of Beirut and complied with the Health Insurance Portability and Accountability Act (HIPAA) recommendations.…”

The influence of soft contact lens wear and two weeks cessation of lens wear on corneal curvature

“…Feb 2014, 37 (1) : 31-37. Introduction A significant proportion of candidates for CRS wear SCLs.SCL wear can result in changes to the corneal structure and metabolism. The time required for resolution of these changes can vary according to contact lens (CL) material, modality and length of previous CL wear [2][3][4].The FDA guidelines recommend that SCLs are left out for at least two weeks prior to initial consultation, however no specific guidelines are given in relation to SCL type, modality or previous years of SCL wear [1].To the author's knowledge, no published study has examined retrospective findings from a SCL group of various lens materials and years of SCL wear and evaluated corneal stability following two weeks lens cessation, in relation to a NCL group.…”

“…The amount of time required to eliminate the alterations to corneal curvature is dependent on CL material, modality and years of previous SCL wear [3,4,[19][20][21]. Corneal curvature measurements show stability following two weeks cessation of SCL wear for most patients [2]. However, in some cases, resolution of stability of corneal measurements can take weeks or months following cessation of SCL wear [3,16,20,21].…”
