Abstract:
Objective To evaluate the therapeutic efficacy of soft contact lenses on corneal diseases. Methods A total of 70 cases (82 eyes) of corneal diseases in the treatment group were treated with therapeutic soft contact lenses combined with topical antibiotic eye drops and artificial tears, but 64 cases (81 eyes) suffering from corneal diseases in the control group were treated with eye drops and eye ointments. ? 2 test was used to compare the cure rate of corneal epithelial defects and corneal ulcers caused by chemical and thermal burns between the two groups. Double sample t test was used to compare the average treatment time between the two groups. Results The cure rates of the corneal epithelial defects and corneal ulcers caused by chemical injury and thermal burn in the treatment group and the control group were 83% and 57%, respectively. In the treatment group, 100% patients with bullous keratopathy and 90% patients with dry eye disease were free from symptoms after wearing the lenses, but in the control group, the percentages were 50% and 63.6%, respectively. In the treatment group, 3 cases (4 eyes) of corneal epithelial defects caused by explosive injury and 3 cases of corneal epithelial defects after lameller keratoplasty were all cured, and 4 cases(4 eyes) of corneal perforations were healed. In the control group, 1 out of the 2 cases of corneal epithelial defects caused by explosive injury was cured, and 4 cases of corneal epithelial defects after lamellar keratoplasty surgery were cured, but 2 cases (2 eyes) of corneal perforation failed in the therapy, and corneal surgery was performed. In the treatment group, the cure rates of corneal epithelial defects or corneal ulcers caused by chemical injury and thermal burn were significantly higher than those in the control group ( P
