Purpose: Eyelid changes have been reported with silicone hydrogel contact lenses. It is hypothesized that those changes are associated with the mechanical interaction between the contact lens front surface and eyelid tissues and, are specific to contact lens type rather than a general effect of the lens category. The purpose of this study was to assess the effect of refitting into a silicone hydrogel on a daily wear basis to current contact lens wearers, lapsed wearers and neophytes on eyelid physiology.
Methods: The investigation was a 2-year prospective investigation of ACUVUE® OASYS® with HYDRACLEAR® Plus (senofilcon A) used with care systems, representative of current practice.
Results: 90 subjects were enrolled of whom 64 subjects completed the investigation. The results obtained were as follows:
Conclusions: The results of the study demonstrated that senofilcon A, worn on a daily wear basis and replaced every 2 weeks, did not produce any eyelid tissue changes in previous non-contact lens wearers at baseline and revealed no change or a slight improvement of the eyelid tissues of established contact lens wearers.

A woman in her 50s underwent simple limbal epithelial transplantation (SLET) in the left eye for chemical injury with total limbal stem cell deficiency. A seroma, a hitherto unreported complication of the procedure was noted on the 10th postoperative day. It was associated with an accumulation of inflammatory cells and exudates in the inferior part of the amniotic membrane resembling a hypopyon.

Purpose: To determine the countrywide prevalence of dry eye disease (DED) at the population level in Spain, and associated risks.
Methods: This was a cross-sectional study based on a telephone survey conducted in 2022. Participants from the general population were selected by sex, age, region, and population of residence to ensure the representativeness of the Spanish population.
Repeatability of lipid layer thickness using LipiView® following removal of contact lenses and its relationship to comfort.

Purpose: To assess the repeatability of lipid layer thickness (LLT) measurement using the LipiView® interferometer after daily disposable contact lens (CL) wear and correlation with ocular comfort in soft contact lens wearers.
Methods: A prospective study was conducted over two consecutive months, wherein CL wearers (n = 20) wore either Somofilcon A or Verofilcon A daily disposable CLs in a crossover design, switching lenses after 1 month. The pre-corneal tear film LLT was measured at the end of each month after CLs had been worn for at least 6 h.
Quantifying tear exchange during rigid contact lens wear using corneoscleral profilometry: A proof of concept study.

Introduction: Tear exchange during contact lens wear is essential for ocular surface integrity, facilitating debris removal, and maintaining corneal metabolism. Fluorophotometry and fluorogram methods are typically used to measure tear exchange, which require hardware modifications to a slit lamp biomicroscope. This manuscript introduces an alternative method using a corneoscleral profilometer, the Eye Surface Profiler (ESP), to quantify tear exchange during corneal and scleral rigid lens wear by assessing fluorescence intensity changes over time.

More than 70% of human information comes from vision. The eye is one of the most attractive sensing sites to collect biological parameters. However, it is urgent to develop a cost-effective and easy-to-use approach to monitor eyeball information in a minimally invasive way instead of current smart contact lenses or camera-based eyeglasses.
