Comparison of effectiveness of silicone hydrogel contact lens and hydrogel contact lens in patients after LASEK

AIM: To conduct a comparative study of effectiveness of silicone hydrogel contact lens and hydrogel contact lens, which are used in patients after laser-assisted subepithelial keratomileusis (LASEK). METHODS: Sixty-three patients (121 eyes) with a spherical equivalent ≤-5.0 D were chosen after undergoing LASEK in 2012 at Guangdong General Hospital. They were randomly divided into 2 groups. The silicone hydrogel group included 32 cases (61 eyes) that wore silicone hydrogel contact lenses for 4-6d after the operation, while the hydrogel group included 31 cases (60 eyes) who wore hydrogel contact lenses for 4-6d after the operation. Patients’ self-reported postoperative symptoms (including pain, photophobia, tears, and foreign body sensation) were evaluated. The healing time of the corneal epithelium, the visual acuity of patients without contact lens after epithelial healing, and the incidence of delayed corneal epithelial shedding were also assessed. The follow-up time was 1mo. RESULTS: Postoperative symptoms were milder in the silicone hydrogel group than in the hydrogel group. There were significant differences in pain, foreign body sensation, and photophobia between the 2 groups (P<0.05), although there was no significant difference in postoperative tearing (P>0.05). The healing time of the corneal epithelium in the silicone hydrogel lens group was markedly shorter than that in the hydrogel group (4.07±0.25 vs 4.33±0.82d, t=2.43, P=0.02). Visual acuity without contact lenses after healing of the corneal epithelium was better in the silicone hydrogel group compared with the hydrogel group (χ2=7.76, P=0.02). There was no significant difference in the occurrence of delayed corneal epithelial shedding between the 2 groups (P>0.05). CONCLUSION: Patients with LASEK using silicon hydrogel contact lenses had less discomfort and shorter corneal epithelial healing time compared with those using hydrogel contact lenses, suggesting that silicon hydrogel contact lenses may be considered to be a better choice of bandage contact lens after LASEK.     

Comparison of efficacy of two different silicone hydrogel bandage contact lenses after T-PRK

AIM:To compare the efficacy between two different silicone hydrogel bandage contact lenses after transepithelial photorefractive keratectomy(T-PRK).METHODS:In this randomized controlled trial,a total of 89 patients(178 eyes) who underwent T-PRK at the Qingdao Eye Hospital from October to December 2019 were selected.One random eye wore a Senofilcon A bandage contact lens after surgery,and the other eye a Balafilcon A bandage contact lens.Pain scores,uncorrected visual acuity(UCVA),spherical equivalent(SE),corneal epithelial healing status,epithelial thickness,bandage lenses deposits,lenses movement,and ocular surface conditions were measured and compared.RESULTS:There were no differences between the two groups in UCVA,SE,corneal epithelial healing status,corneal epithelial thickness,tear river heights and tear film rupture time at each follow-up visit.However,postoperative pain scores in the Senofilcon A group were significantly lower than those of the Balafilcon A group(F_intergroups=67.833,P<0.001;F_time=383.773,P<0.001;F_interaction=57.344,P<0.001).The duration of pain in eyes in the Senofilcon A group was shorter than that of the Balafilcon A group(t=-3.326,P=0.001).The surface deposition scores and movement scores of Senofilcon A bandage lenses on the first and fourth days after surgery were lower than those of Balafilcon A bandage lenses(Z=-5.385,-6.782,P<0.001;Z=-8.336,-8.906,P<0.001).CONCLUSION:Both Senofilcon A and Balafilcon A bandage lenses have good efficacy after T-PRK.Senofilcon A lenses are associated with less pain and more comfort compared to Balafilcon A.     

Clinic study on silicone hydrogel contact lenses used as bandage contact lenses after LASEK surgery

AIM: To compare the clinical performance of two types of silicon hydrogel contact lenses used as bandage lenses after LASEK surgery. METHODS: A prospective, double-masked study was conducted on 42 eyes of 21 patients who received binocular LASEK surgeries. The interocular difference in spherical equivalent power was less than -1.50D. Patients were randomly assigned to wear Galyfilcon A (Lens A) bandage contact lens in one eye and Balafilcon A (Lens B) in the fellow eye after the surgery. The responses to a subjective questionnaire on comfort of wearing, corneal epithelial status, conjunctival hyperemia, limbal neovascularization, lens fitting and contact lens debris were assessed 1 and 5 days postoperatively. Corneal endothelium was assessed before and 5 days after the surgery upon bandage lens removal. RESULTS: There was no difference between the two groups in terms of conjunctival hyperemia, limbal neovascularization, contact lens fitting, corneal epithelial status, corneal endothelium cell density (CD) and endothelium cell size (CS) at any postoperative visit. Complaints of discomfort, including foreign body sensation, pain and intolerance were statistically more among Lens B wearers at any postoperative visit (P<0.05). Lens B appeared to attract much more debris than Lens A at the 5-day post-operative follow-up visit (P<0.01). CONCLUSION: The two types of silicon hydrogel lenses investigated in this study demonstrated similar clinical performance in terms of corneal responses and lens fitting. However, Lens A showed a better performance in terms of comfort of wearing and deposit resistance.     

Comparison of silicone and non-silicone hydrogel soft contact lenses used as a bandage after LASEK

PURPOSE: To evaluate two different soft contact lens materials for continuous-wear bandage contact lenses after laser epithelial keratomileusis (LASEK). METHODS: A prospective, observer-masked study was conducted of 32 eyes of 16 consecutive patients. Inclusion criteria were candidates for bilateral LASEK, myopia of < or = -6.00 diopters (D), astigmatism < -1.50 D, and bilateral best spectacle-corrected visual acuity of 20/20 or better. Patients were randomly selected for a balafilcon A (PureVision; Bausch & Lomb) bandage contact lens in one eye and a poly-2-hydroxyethylmethacrylate-co-methacrylate glycerol (EquiS 60; mark'ennovy) in the fellow eye. Corneal epithelial status, conjunctival and limbal hyperemia, lens movement, contact lens debris, and the responses to a subjective comfort questionnaire were assessed postoperatively. The parameters were evaluated preoperatively and 1 and 5 days postoperatively. Paired Student t test and chi-square tests were used when appropriate. RESULTS: Thirty-two eyes of 16 consecutive patients who underwent LASEK to correct low to moderate myopia were analyzed. The mean spherical equivalent refraction was -3.25 D. There was no difference in conjunctival or limbal hyperemia, contact lens debris, or subjective comfort between lenses at any postoperative visit. In contrast, the corneal epithelial status was statistically better in the eyes with a silicone bandage contact lens 5 days after LASEK (P = .01). CONCLUSIONS: The results suggest that the bandage contact lens material used after LASEK affects the corneal epithelial healing process.

A comparative study of biweekly disposable contact lenses: silicone hydrogel versus hydrogel

Background: Our aim was to compare the clinical performance of a biweekly (second generation) silicone hydrogel lens and a biweekly hydrogel lens worn for daily wear modality. Methods: We used a double‐masked study, in which non‐presbyopic, asymptomatic and adapted soft lens wearers were recruited. Subjects wore a silicone hydrogel lens in one eye and a hydrogel lens in the other (lens types and eyes were randomly assigned) for one month. Lenses were replaced every two weeks. Contact lens fitting, pre‐lens tear film thinning time, vision, corneal integrity and lens deposits were assessed before and every fortnight after delivery of new lenses. A questionnaire was used to compare the subjective performance of the two lens types. Results: Thirty of the 33 subjects completed the study. There were no significant differences in lens fitting (centration and movement), pre‐lens tear film thinning time, vision or corneal integrity between the two lens types. Statistically, there was no significant difference in lens deposits between the two lens types but silicone hydrogel lenses tended to have more Grade 3 to 4 lipid deposits than hydrogel lenses. Subjects found no significant differences between the two lens types in terms of vision and comfort. Preference for silicone hydrogel lenses increased from 33 at the first after‐care visit to 50 per cent at the second after‐care visit. Conclusion: This short‐term study demonstrates that the performance of silicone hydrogel and hydrogel lenses is comparable but the former tends to build up more lipid deposits than the latter. We did not find better performance in terms of ocular integrity of silicone hydrogel lenses compared to the hydrogel lenses, probably because the subjects were adapted asymptomatic contact lens wearers before commencing the study. Contact lens wearers having hypoxia‐related problems are likely to benefit from using silicone hydrogel lenses, as these lenses provide at least three times more oxygen than conventional hydrogel lenses.     

溴芬酸钠与氟米龙在LASEK术后应用的疗效比较

目的 比较溴芬酸钠与氟米龙滴眼液在准分子激光角膜上皮瓣下磨镶术（LASEK）后对眼部刺激症状的效果及其临床应用的安全性。方法 前瞻性随机对照研究。选取2017年4月至2018年2月在天津市眼科医院接受LASEK手术的近视及近视散光患者60例（120眼）作为研究对象,参照随机数字表法分为溴芬酸钠组和氟米龙组,每组各30例（60眼）。术后第1周,除常规用药外,溴芬酸钠组给予0.1%溴芬酸钠滴眼液每日2次,1周后改为每日4次,1个月后改为每日2次,再滴眼1个月后停药。术后第1周,氟米龙组给予0.3%玻璃酸钠滴眼液每日2次,1周后停用0.3%玻璃酸钠滴眼液,改用0.1%氟米龙滴眼液,每日4次,每月递减1次,4个月后停药。于术后1、2、3、5 d观察2组角膜刺激症状及上皮愈合情况。术后1周、1个月、3个月行裸眼视力（UCVA）、最佳矫正视力（BCVA）、综合验光、裂隙灯显微镜、泪液分泌试验（SⅠT）、泪膜破裂时间（BUT）和角膜上皮完整性评估等检查。术后1周、2周、1个月、3个月、4个月行非接触式眼压测量。采用重复测量方差分析、独立样本t检验和Mann-Whitney U检验对数据进行统计分析。结果 术后溴芬酸钠组角膜刺激症状评分明显低于氟米龙组,差异均有统计学意义（F_组别=7.8,P=0.018;F_时间=121.7,P<0.001;F_交互作用=273.4,P<0.001）。术后1个月时,2组患者LogMAR视力均优于0.0以上,2组各时间点UCVA及BCVA对比差异无统计学意义。术后2组患者屈光度稳定,2组间比较差异无统计学意义（F_组别=1.0,P=0.137;F_时间=1.3,P=0.121;F_交互作用=1.1,P=0.272）。术后1个月时,溴芬酸钠组6眼（10%）发生角膜上皮下混浊（haze）,氟米龙组2眼（3%）发生haze。术后溴芬酸钠组各时间点眼压校正值均<21 mmHg;氟米龙组术后2周时有5眼（9%）眼压升高,术后1个月时有3眼（5%）眼压升高。术后3个月,2组的SⅠT和BUT均大致恢复到正常水平,差异无统计学意义。术后3个月,2组中大部分病例角膜上皮均完整,无荧光着染,2组间比较差异无统计学意义。结论 溴芬酸钠滴眼液能有效减轻LASEK术后眼部刺激症状,在术后视力恢复及抗炎作用方面安全有效,同时能减少糖皮质激素导致的术后高眼压风险,但角膜haze的发生率较氟米龙略高。
