Purpose: Microcornea is a rare condition that frequently resulets in serious cosmetic concerns due to the resultant asymmetrical appearance of the eye, and its cosmetic rehabilitation is possible with the use of colored contact lenses. This paper aims to present our experiences with the use of cosmetic Etafilcon A contact lenses for microcornea.
Methods: Eight patients with unilateral microcornea without any systemic involvement were included in this study, and they underwent routine ophthalmological examination, corneal topography, and optical biometry. We applied the cosmetic Etafilcon A contact lens (1-DAY ACUVUE® DEFINE® with Lacreon®) of the same edge color to the patients. The levels of satisfaction in terms of cosmesis and comfort were evaluated with the use of visual analog scales (VAS).
Results: In the patients, the corneal diameter asymmetry was acceptably adjusted, and each of the patients reported extreme satisfaction. The mean VAS score was 8.9 ± 1.0 (range: 7-10) for the cosmetic satisfaction rate and 8.4 ± 1.0 (range: 7-10) for the comfort rate. The patients obtained the best-corrected visual acuity without or with additional eye-glasses. None of the patients complained about vision issues under photopic and scotopic conditions.
Conclusion: 1-DAY ACUVUE® DEFINE® with Lacreon® lens has promising satisfactory cosmetic outcomes along with visual enhancement in cases of microcornea. This is the first study to report the use of this lens for the cosmetic rehabilitation of patients with microcornea.

Purpose: Prelens tear film stability of soft contact lens (SCL) play an important role for contact lens discomfort. In this study, we investigated the association between two types of noninvasive methods and evaluated the tear film stability with SCL using the methods.
Patients And Methods: In experiment 1, images of ring mire were recorded with a keratograph after focusing the pigment located at the front or back of the SCL.

Purpose: To compare the sensitivity of two genotypes of P. aeruginosa to various disinfectant solutions and analyze the attached bacteria on worn cosmetic contact lenses (cosCLs).
Methods: In this prospective study, healthy volunteers wore etafilcon (brown), nelfilcon (gray), or hilafilcon (black) cosCLs and microbial adhesion analysis was performed.

Purpose: To evaluate the individual contributions of pigment colorant and packing solution containing polyvinyl pyrrolidone (PVP) on the oxygen permeability (Dk) of a cosmetic printed etafilcon A daily disposable contact lens packaged with PVP.
Method: The oxygen transport of a contact lens is evaluated through the central optical zone of the lens. Cosmetic printed contact lenses contain pigment colorant in the periphery or mid-periphery of the lens.

Purpose: To determine if the use of pigments or adding polyvinyl pyrrolidone during the fabrication of 1-DAY ACUVUE DEFINE (AD) brand contact lenses impacts open-eye corneal swelling compared with no lens wear (NLW).
Methods: A partial double-masked, randomized, bilateral crossover study was conducted in 24 Asian subjects using AD, 1-DAY ACUVUE DEFINE with Lacreon (ADL), NLW, and a control lens with no tint (1-DAY ACUVUE MOIST [AM]). Central corneal thickness was measured before insertion and immediately after removal after 8 ± 1 h of open-eye wear using an optical pachymeter in one eye.
