关键词： Femtosecond laser LASIK Location of gas diffusing canal Opaque bubble layer

摘要：
• AIM: To investigate the predictive factors of the opaque bubble layer (OBL) compared to the fellow eye of same patients in FS200 femtosecond laser assisted laser in situ keratomileusis (FS-LASIK). • METHODS: This study consisted of 60 consecutive patients (120 eyes) with unilateral OBL during FS-LASIK. Eyes were divided into OBL (the OBL eyes) and OBL-free groups (the fellow eyes) based on the occurrence of OBL. The preoperative demographic data, refraction, keratometry, corneal astigmatism, pachymetry, intraocular pressure and intraoperative data including the outlet location of gas diffusing canal were collected. Conditional logistic regression analysis was performed to find the associated factors with OBL in the two groups by determining odds ratios (OR) and 95%CI. • RESULTS: The preoperative demographic data, mean spherical errors, mean K value, suction time, intraocular pressure and central cornea thickness were not significantly different between the two groups. The outlet location of gas diffusing canal (P<0.01, OR 7.16, 95%CI 2.53-20.32) and the corneal astigmatism (P=0.013, OR 0.13, 95%CI 0.03-0.65) were significantly associated with the incidence of OBL by multivariate logistic regression analysis. Visual acuity, efficacy, and safety were comparable between the two groups two months after surgery except for a slightly lower predictability value for the hard OBL eyes. • CONCLUSION: The reduction of the incidence of OBL is obvious when the outlet of gas diffusing canal located at the posterior border of the corneoscleral limbus. This is probably consequent to more effectiveness of gas diffusing canal. Corneal astigmatism is also an independent protective factor for OBL formation. © 2019, International Journal of Ophthalmology (c/o Editorial Office). All rights reserved.

no diffusion space. The gas accumulated in the corneal stromal bed and led to hard OBL. When the canal outlet was located at the sclera, despite was impassable, the canal could accommodate partial gas and slight soft OBL occurred. When the canal outlet was located at the posterior border of the corneoscleral limbus, soft OBL was more common because some canal were partial unobstructed and could diffuse some gas. At present, the published literature preliminarily considers that OBL doesn’t influence the excimer laser ablation effect or postoperative uncorrected and corrected visual acuity[14]. But severe hard OBL can disturb eye tracking of excimer laser. Our results showed that the refractive status of the OBL eyes 2mo after surgery was more inclined to be negative, but it didn’t reach statistical difference. In summary, keeping the gas diffusing canal unobstructed is one of the key points to decrease the incidence of OBL in FS-LASIK using FS200 FSL machine. When the outlet of gas diffusing canal was located at the posterior border of the corneoscleral limbus, the high patency rate could be obtained, thus the incidence of OBL was low. Corneal astigmatism was also a independent protective factor for OBL formation. However OBL is the result of many factors, so reducing the incidence of OBL needs the development in the technological and clinical fields.
