“…[25] Wolffsohn et al showed that tear break-up time over the daily contact lens surface differed between lens types and may have a role in protecting the ocular surface [21]. Several authors did not observe any changes over time in contact lens wearers [21,26,27] using silicone hydrogel daily contact lenses at 8, 12, and 16 h of wear on one day. The findings of this study are in agreement with those found in earlier studies.…”

The aim of the current study is to assess, using new technologies, the interaction of four monthly silicone hydrogel contact lenses on the ocular surface and the comfort over 15 days of use. Methods: Prospective cross-over, randomized and double-masked study including four materials (lotrafilcon-B, samfilcon-A , comfilcon-A and filcom-V3). Clinical examination was performed in the following order: tear meniscus height, first break-up of the tear film, the average time of all tear film breakup incidents, bulbar redness, limbal redness (Keratograph 5M ,Oculus, Germany); central corneal thickness (Pentacam, Oculus, Germany), thermography values (FLIR A325; FLIR Systems Inc., USA), and slit-lamp evaluations, including ocular surface staining. Finally, subjective comfort was obtained from Contact Lens Dry Eye Questionnaire-8. Results: The impact of contact lens wear on the ocular surface didn't show statistically significant changes over time except for corneal and conjunctival staining grades on day 15 compared to day 1 for the comfilcon A group (P = .003 and P = .01, respectively). Contact lens stability and impact on the ocular surface during contact lens wear didn't show statistically significant changes over time except in the case of the comfilcon A material with respect to the irritation item (P = .01). Conclusions: These results suggest that the impact of monthly silicone hydrogel contact lens materials on the ocular surface after and during contact lens wear, contact lens stability over time, and subjective comfort did not reveal any significant changes over 15 days of use for any of the materials.

“…Significant efforts have been made to minimize the impact of SiH materials on the tear film by making the surfaces more wettable; to date, these include surface treatments, internal and external wetting agents, water gradient surfaces and the incorporation of hydrophilic monomers [128]. As a result, the on-eye wettability of SiH materials has been shown to be very similar to that typically observed with hydrogel materials [128,[131][132][133][134].…”

“…Three SiH DD contact lenses (delefilcon A, narafilcon A and somofilcon A) were compared in a short-term randomized, cross-over study in both symptomatic and asymptomatic contact lens wearers [133]. All three lens types performed well with respect to surface deposits, wettability, pre-lens noninvasive tear breakup time, lens movement, and centration.…”

Daily disposable (DD) contact lenses first came to the market approximately 25 years ago and eye care professionals (ECPs) started prescribing silicone hydrogel (SiH) contact lenses, primarily for extended or continuous wear, approximately 20 years ago. It has now been over ten years since SiH DD contact lenses have been available, and while SiH materials are routinely prescribed by ECPs for reusable daily wear, hydrogel materials are still frequently selected for the DD modality of contact lens wear. This article reviews the evidence to support the benefits of both a DD modality and SiH materials and how patients' needs may be met with SiH DD contact lenses, with respect to clinical performance, health outcomes, satisfaction, compliance and convenience. Factors which may enable or constrain ECPs from prescribing SiH DD contact lenses, as opposed to hydrogel DD and reusable contact lenses, for more of their patients are discussed with the objective of providing ECPs with a greater understanding of the advantages that can be afforded by prescribing SiH DD contact lenses to both their new and existing contact lens wearers.
