Methods: Oxygen permeability in central and peripheral areas of clear and circle lenses made of nelfilcon A, hilafilcon B, and etafilcon A was measured by the polarographic method after incubation in phosphate buffer solutions with pHs of 6.6, 7.4, and 7.8, respectively, for 24 hours. Oxygen transmissibility was calculated after measuring the thickness of the central and peripheral areas of the soft lenses. Results: The oxygen transmissibility of the clear central area without pigmentation showed an increasing tendency with increasing pH, except in the nelfilcon A circle lens. On the other hand, the oxygen transmissibility of the peripheral area, which differs in pigmentation, showed an increasing tendency with increasing pH, except in the nelfilcon A clear lens. In addition, the degree of change in the oxygen transmissibility of the soft lenses made of the same material was greater in the central area of the clear lenses than in the circle lenses. For the peripheral area, the degree of change was tended to be greater in the circle lenses than in the clear lenses. Conclusions: From these results, it was revealed that the changes in oxygen transmissibility of soft lenses induced by pH changes depended on the pigmentation and the lens location. The change in oxygen transmissibility of circle lenses appeared to be primarily affected by oxygen permeability or lens thickness. Therefore, pH changes can result in changes of comfort and vision correction or the occurrence of complications in clinical trials, depending on the materials and pigmentation of soft lenses.","PeriodicalId":178533,"journal":{"name":"Journal of Korean Ophthalmic Optics Society","volume":"146 8‐12","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132340186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods: Thirty-three subjects (65 eyes) with no history of refractive keratoplasty or eye diseases were fit with multi-curve spherical soft contact lenses after identifying the corneoscleral shape profiles on the superior and inferior ocular surfaces. The subjects were categorized under groups based on the corneoscleral shape profile, and decentration, post-blink movement, lag, and push-up test were examined. The groups were compared based on the test items, and the fitting statuses were checked. Results: On the superior ocular surface, the group with a fluid convex or tangential corneoscleral transition showed significantly larger post-blink movement (p = 0.000) and temporal (p = 0.003), nasal (p = 0.001), and inferior (p = 0.021) lags, and relatively loose fitting (p = 0.041) compared to the group with a marked convex or tangential corneoscleral transition. On the inferior ocular surface, the group with a fluid convex or tangential corneoscleral transition showed significantly larger post-blink movement (p = 0.000) and nasal (p = 0.001) and inferior (p = 0.049) lags, and relatively loose fitting (p = 0.021) compared to the group with a marked convex or tangential corneoscleral transition. Conclusions: Designing the back surface of a soft contact lens based on the corneoscleral shape profile provides a more appropriate fitting condition.","PeriodicalId":178533,"journal":{"name":"Journal of Korean Ophthalmic Optics Society","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125563665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
