Purpose: We report a case of corneal warpage secondary to hydrogel lens wear that was initially mistaken as a case of keratoconus.
Methods: A 26-year-old Chinese female hydrogel lens wearer presented with an interest in refractive surgery. After topographies and pachymetries were performed, keratoconus was initially diagnosed for her right eye and suspect keratoconus diagnosed for her left eye. This conclusion was felt to be confirmed at a follow-up visit 1 week later, but keratoconus contact lens treatment was delayed because of the presence of superficial punctate keratitis.
Results: After 8 weeks without lens wear, corneal maps were performed again. The maps now showed regular with-the-rule astigmatism, and none of the previous evidence of keratoconus. Central pachymetries were also normal.
Conclusions: Soft contact lens wear can induce corneal warpage mimicking keratoconus. Had the standard treatment for keratoconus been implemented before resolution of the warpage, it could have proven injurious to the patient, because the treatment itself could have provided an impetus for the protrusion to remain or perhaps even progress. Our case gives clinicians reason to pause when dealing with contact lens wearers presenting with corneal curvature irregularities such as keratoconus or ectasia, because of the possibility of lens-induced warpage.

Repeatability of lipid layer thickness using LipiView® following removal of contact lenses and its relationship to comfort.
Ophthalmic Physiol Opt
January 2025
School of Optometry and Vision Science, University of New South Wales, Sydney, New South Wales, Australia.
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.
Ophthalmic Physiol Opt

Contact Lens and Visual Optics Laboratory, Optometry and Vision Science, Centre for Vision and Eye Research, Queensland University of Technology, Brisbane, Queensland, Australia.
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.

Objective: To determine whether there is a loss of treatment effect (rebound) after discontinuing soft multifocal contact lenses in children with myopia.
Design, Setting, And Participants: The Bifocal Lenses in Nearsighted Kids 2 (BLINK2) cohort study involved children with myopia (aged 11-17 years at BLINK2 baseline) who completed the BLINK Study randomized clinical trial.
Quarter of a century of contact lens prescribing trends in Australia (2000-2024).
Clin Exp Optom
January 2025
Eurolens Research, Division of Pharmacy and Optometry, The University of Manchester, Manchester, UK.
Clinical Relevance: Knowledge of contact lens prescribing trends can (a) assist practitioners to benchmark their own prescribing habits, (b) help the contact lens industry understand preferred products, and (c) support academics in scholarly writings.
Background: This work aims to document contact lens prescribing trends in Australia over the past quarter of a century.
Methods: An annual survey of contact lens prescribing trends was conducted in Australia each year from 2000 to 2024, inclusive, by asking optometrists to provide information relating to 10 consecutive contact lens fits undertaken between January and March.
Scleral lens wear and fluid reservoir turbidity in eyes with ocular surface disorders.
Ophthalmic Physiol Opt
January 2025
Elite School of Optometry, Medical Research Foundation, Chennai, India.
Purpose: To investigate changes in fluid reservoir turbidity parameters over time and its influence on visual performance in eyes with ocular surface disorders (OSD) wearing scleral contact lenses (SL).
Methods: Thirteen eyes with OSD were assessed for corrected distance visual acuity, contrast sensitivity (CS) and fluid reservoir turbidity using anterior segment optical coherence tomography at baseline, after 5 min and 0.5, 1, 2, 3 and 4 h of SL wear on day 1 and after 1 month.
