Abstract Details


To report visual,refractive, topographic and biomechanical outcomes of simultaneous small inicsion lenticule extraction [SMILE] and intrastromal crosslinking in eyes with abnormal topography and forme fruste keratoconus.


Roayah vision correction center international femto lasik center


Prospective case series of 118 eyes of 66 patients.Inclusion criteria were topographic diagnosis of forme fruste KC,stable refraction and topographic findings for at least 1 year, BCVA>0.7, central corneal thickness >460u, patient age >21 years, follow up at 1 day,1 week,1,3,6,9,12 months.UCVA,BCVA,manifest refraction,topographic,clinical evaluation,IOP and biomechanical stability of the cornea assessed.SMILE was preformed ,all cases had a 100u cap and 300u residual stromal bed followed by intra-pocket injection of isotonic riboflavin then 3 min 30 mw/cm2 UV cross-linking.Bio-mechanical stability was assessd using the Corvis ST measuring and correlating IOP and deformation amplitude.


Mean patient age was 29.4+/-5.63(22-35).Mean preoperative UCVA 0.13+/-0.08 and 0.82+/-0.13 postoperative. Mean preoperative refracton was -3.97±1.87 D sphere(range -6.0 to -1.25) and -2.85 D cylinder (range -0.75 to -4.25), mean postoperative SER was -0.14±0.73 D (range -1.25 to +1.5)mean astigmatism was -0.18 ± 0.45 D. 72% within +/- 0.5 and 89% within +/- 1.0 D. 2 eyes lost 1 line of BCVA, 1 eyes lost 2 lines due to haze. Some patients presented intrastromal haze that improved during the follow-up. Mean deformation amplitude was 1.38 mm ±0.29 pre-op. to 1.19 mm ±0.29 postop while pre and post-operative IOP showed no significance.


Combined SMILE and crosslinking is a safe, predictable and stable treatment option in patients where conventional laser refractive surgery is contraindicated.Further follow-up and larger samples are needed
