SMILE BEYOND VIRGIN EYES Dr. Moones Abdalla, MD, Cornea Center, Alexandria, Egypt

My speech is based on the my own professional opinion or on our study results. It is not necessarily a reflection of the point of view of Carl Zeiss Meditec AG and may not be in line with the clinical evaluation or the intended use of their medical devices. ZEISS therefore recommends that you carefully assess suitability for everyday use in your practice.

SMILEs special characteristics gave us the opportunity to  explore a whole new world of cutting-edge technology and  contributing to the evolution of refractive surgery. Biomechanical advantages, tailored optical zone, cap diameter and the concept of being flapless encouraged us to use SMILE as a tool not only  to enhance residual refractive errors but also  in other challenging situations.

1. SMILE for post-keratoplasty myopia and astigmatism  Centered within the graft, preserving graft biomechanics  Within the graft no flap creation  no changing of refraction  Preserving the biomechanic of recipient tissue

2. SMILE & Refractive Lenticule Implantation (Re-L- Imp) For Unilateral Aphakia Lenticule implantation as an options for  hyperopic,  keratoconus and  presbyopic corrections Video

3. SMILE within an old thick flap – LASIK enhancement Video

4. SMILE for Post-ICRs & CXL Residual Myopia & Astigmatism  Repeatable centration  precise optical zone measurement s Video

4. SMILE for Post-ICRs & CXL Residual Myopia & Astigmatism - RESULTS

5. Sub-SMILE (Small-Incision Lenticule Extraction) Enhancement: A New Retreatment Option „ Retreatment strategies following Small Incision Lenticule Extraction (SMILE): In vivo tissue responses .“ Riau AK, Mehta JS et all PLoS One 2017 Jul 14; 12 (7)

5. Sub-SMILE (Small-Incision Lenticule Extraction) Enhancement: A New Retreatment Option Conclusion:  Different methods resulted in unique tissue response  S+SE offers minimal inflammation and cell death as well as maintaining flapless minimally invasive characteristics

CASE REPORT SMILE FOR MANAGEMENT OF LASIK COMPLICATIONS

Patient History/Background  A case of microkeratome suction loss was referred.  There was thin, irregular, buttonholed flap.  There was also free cap .  She presented to me with epithelial Ingrowth  A month later she developed partial melting of the flap and scarring

Surgical intervention and course  PTK “100 µ” for removal of the superficial corneal scar was performed.  There was circumferential scar.  With intense steroid treatment the scar decreased significantly .

3 months post PTK results

SMILE surgery 3 months post PTK

Results 1 week post SMILE surgery and conclusion  UCVA: 1.0  Cornea is more or less clear.  Refraction is almost plano.

Take home message/conclusion  SMILE has not reached the limits yet – a lot more options to explore  driving and contributing to the evolution of the refractive surgery  New treatment options/therapeutic treatments for “hopeless eyes”
