Does facial mask use make our eyes dry? Change in tear meniscus measurements and conventional dry eye tests during facial mask use
(2022) Hasan Basri ARİFOĞLU; Başak BOSTANCI CERAN; Emin Emrullah TAŞINDI; Serdar ÖZATEŞ
Purpose: The objective of the study is to evaluate the effect of mask use on tear meniscus (TM) measurements obtained by anterior segment optical coherence tomography (AS-OCT) and on conventional dry eye tests. Methods: Right eyes of 86 healthy individuals were included in the study. Lower TM parameters were measured with ASOCT and TM height (TMH) and depth (TMD) were calculated with facial masks on and 1 h after taking the masks off. Schirmer’s and tear break up time (TBUT) tests were measured under the same circumstances. Results: Mean age of the individuals was 34.4±9.6 years. Of the 86 individuals, 40 (46.5%) were male and 46 (53.5%) were female. Mean age did not differ between genders (p=0.309). Mean TMH and TMD were significantly lower in individuals with face mask (p<0.001, p<0.001, respectively). TBUT score was significantly lower in individuals with face mask (p<0.001). The mean Schirmer score did not significantly change between measurements (p=0.471). The mean mask on and mask off TMH, TMD, Schirmer’s test, and TBUT outcomes did not significantly differ between males and females in the study (p>0.05 for all). Conclusion: Wearing facial masks seem to affect the TM parameters and decrease TBUT of the patients. This may explain the irritation symptoms in the eyes of the patients when using masks. Appropriate measurements should be taken in order to relieve these ocular symptoms, since wearing masks become a daily routine of our lives for protection against airborne pathogens.

Epithelial Thickness Profile Change After Corneal Crosslinking: A Retrospective Research
(2021) Akif ÖZDAMAR; Serdar ÖZATEŞ; Başak BOSTANCI CERAN; Şennur KALENDER
Objective: To assess the corneal epithelial remodeling after corneal crosslinking (CXL) and to investigate the relation between topographic parameters and epithelial thickness change. Material and Methods: Sixty-three eyes of 43 keratoconus patients were included in this retrospective study. Keratometry (K) and elevation data were assessed by Scheimpflug topography and corneal and epithelial thickness profile was obtained by anterior segment spectral-domain optical coherence tomography pre-operatively and at the 1st, 6th and 12th months after CXL. Results: Significant decreases were observed in mean K (p=0.014), maximum K (p=0.049), and mean central corneal thickness (p<0.007) after CXL. Superior corneal epithelial thickness was significantly thinner (p<0.001) and the difference between the minimum and maximum epithelial thickness was less at the post-operative first month and didn’t change significantly afterwards. Standard deviation of epithelial thickness across the central 5 mm region statistically decreased in the follow-up period (p=0.008). Conclusion: Significant regularization of the epithelial thickness profile was seen in one year after epithelium-off CXL. Demonstrating the normalization of the corneal epithelium and understanding its impact on the post-operative healing process might contribute to the optimization of treatment protocol.

Refractive results, visual quality and patient satisfaction with a new trifocal intraocular lens design
(2020) Hasan Basri ARİFOĞLU; Serdar ÖZATEŞ; Emin Emrullah TAŞINDI; Başak BOSTANCI CERAN
Aim: To evaluate the outcomes after bilateral implantation of a new trifocal intraocular lens (IOL).Materials and Methods: The study included patients with visually significant cataract that underwent bilateral implantation of theAcriva Trinova Sinusoidal Trifocal IOL. The preoperative corrected distance visual acuity (CDVA) and postoperative uncorrecteddistance visual acuity (UDVA), CDVA, uncorrected intermediate (UIVA) and near visual acuities (UNVA) along with manifest refractionswere assessed at 1 month and 6 months after cataract surgery. The defocus curve and contrast sensitivity (CS) were evaluated atthe 6th month visit. Patient satisfaction and incidence of dysphotopic symptoms were assessed.Results: The study enrolled a total of 60 eyes of 30 patients, 10 males and 20 females aged 61.78± 8.73 years (range, 45 to 78 years).90% of the patients (n: 27) achieved a binocular UIVA of 0.1 LogMAR or better at the 6-month visit while, 96.7% (n:29) patients hada binocular UNVA of 0.1 LogMAR or better in the same postoperative visit. The CS results were within the the range of normalityat 6 months post-surgery. 6.7% of patients reported marked halo around light sources and 3.3% reported glare that interferes withnighttime driving. 96.6% of the patients reported spectacle independence for all distances and rated their visual function and qualitysatisfactory at all distances.Conclusion: Bilateral implantation of the Acriva Trinova Sinusoidal Trifocal IOL seems to provide effective restoration of visualfunction at all distances after cataract surgery in the majority of patients. Contrast sensitivity results and low incidence of dysphotopicphenomena might be associated with high patient satisfaction.
