Effect of diquafosol sodium combined with sodium hyaluronate on improving tear film stability after wearing orthokeratology lens

摘要:

目的：探究地夸磷索钠滴眼液联合玻璃酸钠滴眼液对改善角膜塑形镜配戴后的泪膜稳定性的作用。

方法：前瞻性研究。选取2022-03/08于安徽爱尔眼科医院门诊就诊的初次配戴角膜塑形镜患者82例82眼(均取右眼数据)，根据随机数字表法分为玻璃酸钠组(玻钠组)30眼、地夸磷索钠组(地夸组)24眼和地夸磷索钠联合玻璃酸钠组(联合组)28眼，各组患者均配戴同一品牌的角膜塑形镜。每位患者分别在配戴角膜塑形镜前，配戴后1 d，1 wk，1 mo进行非接触式泪膜破裂时间(NIBUT)、非接触式泪河高度(NITMH)和脂质层厚度检查，并记录患者是否有角膜点染。

结果：联合组与地夸组治疗1 mo的NITMH与NIBUT较配戴前升高(均P<0.05)。配戴1 mo，联合组的NIBUT和NITMH分别为19.74±3.29 s和0.30±0.05 mm，均优于地夸组(NIBUT：16.09±2.98 s，NITMH：0.22±0.08 mm)和玻钠组(NIBUT：15.67±3.90 s，NITMH：0.22±0.04 mm)(均P<0.01)。各组间脂质层厚度均无明显差异(均P>0.05)。各组患者角膜点染发生率无明显区别(P>0.05)。

结论：地夸磷索钠滴眼液联合玻璃酸钠滴眼液在配戴角膜塑形镜后1 mo对改善NIBUT和NITMH有更佳的效果，有效提高配戴角膜塑形镜患者的泪膜稳定性。

Abstract:

AIM:To investigate the effect of diquafosol sodium(SD)eye drops combined with sodium hyaluronate eye drops on improving tear film stability after wearing orthokeratology lenses.

METHODS:Prospective study. A total of 82 patients(82 right eyes)who were recruited from the outpatient department of Anhui Aier Eye Hospital from March to August 2022. Participants were assigned to three groups: sodium hyaluronate(SH)group(30 eyes), SD group(24 eyes), and sodium diquafosol combined with sodium hyaluronate(CG)group(28 eyes)according to random number table method. All groups wore the same brand of orthokeratology lens. Non-invasive tear breakup time(NIBUT), non-invasive tear meniscus height(NITMH)and lipid layer thickness were examined before treatment, and after wearing orthokeratology lens for 1 d, 1 wk, and 1 mo. Corneal spot staining was also recorded.

RESULTS:The NITMH and NIBUT of CG group and the SD group at 1 mo after treatment were higher than those before wearing lenses(both P<0.05), and the NIBUT and NITMH of the CG group were 19.74±3.29 s and 0.30±0.05 mm, respectively, which were better than those of the SD group(NIBUT: 16.09±2.98 s, NITMH: 0.22±0.08 mm)and the SH group(NIBUT: 15.67±3.90 s, NITMH: 0.22±0.04 mm; all P<0.01). There were no significant differences in lipid layer thickness between the groups(all P>0.05). The incidence of corneal staining did not differ significantly among the groups(P>0.05).

CONCLUSION:The combination of diquafosol sodium and sodium hyaluronate eye drops demonstrates a superior effect in improving NIBUT and NITMH after wearing orthokeratology lenses for 1 mo, effectively enhancing tear film stability in patients wearing orthokeratology lenses.
