Abstract The aim of this work is to evaluate the safety and efficacy of T-ICL implantation following corneal collagen crosslinking for correction of myopia and astigmatism in selected cases of keratoconus. 30 eyes of 22 keratoconus patients were included in the study. 6 male (27.3%) and 16 female (72.7 %) patients with age ranged from 21 to 38 years were recruited from the ophthalmology department outpatient clinic at Minia university hospital during the period from October 2013 to May 2016. 8 patients had bilateral surgery and 14 patients had unilateral surgery. CXL was done first then T-ICL implantation after 6 months after CXL and the patients were followed up for 12 months after T-ICL implantation. All patients had keratoconus grade 1 or 2 with clear cornea with ACD equal or more than 3 mm, no cataract or glaucoma and no retinal diseases. For preoperative calculation of the T-ICL power, refraction, K readings, ACD, pachymetry and WTW were needed. Special patient preoperative preparation was needed and a learning curve was needed for the T-ICL loading and implantation. Complete ophthalmic examination was performed at 1st day, 3rd day, 1st week, 2 weeks, 1 month, 3 months 6 months and 12 months after T-ICL implantation. Uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), and refraction, IOP and adverse effects were recorded after 1 month, 3month, 6 months and 12 months after T-ICL implantation. There was significant improvement in spherical and cylindrical errors and visual acuity during the follow up period of 12 months with no postoperative complications. Our results agreed with previous studies about T-ICL in keratoconus after CXL. |
