  1. St.-Petersburg Moscow Kaluga Cheboksary Ekaterinburg Tambov Volgograd Krasnodar Orenburg Novosibirsk Khabarovsk Irkutsk ANTERIOR SEGMENTOCT OF CLEAR CORNEAL INCISIONS AFTER 1.8mm CMICS AND 2.8mm SANDARD COAXIAL CATARACT SURGERY S.FYODOROV EYE MICROSURGERY COMPLEX STATE INSTITUTION MOSCOW, RUSSIA B.MALYUGIN MD,PhD A.GOLOVIN MD FINANCIAL DISCLOSURE B.MALYUGIN – Bausch & Lomb Surgical, MST A. GOLOVIN – Nothing to disclose

  2. PURPOSETO COMPARE THE STRUCTURE OF THE CLEAR CORNEAL TUNNELS DONE FOR THE 1.8 mm C-MICS AND 2.8 mm STANDARD CO-AXIAL PHACO USING THE ANTERIOR SEGMENT OCT

  3. MATERIALS & METHODS I-st GROUP: 20 EYES (20 PATIENTS) 1.8 mm C-MICS with AKREOS MI60 IOL II-nd GROUP: 20 EYES (20 PATIENTS) 2.8 mm SICS with AKREOS AO IOL

  4. MATERIALS & METHODS PHACO SETTINGS QUICK CHOP IV POLE HEIGHT - 100 cm DUAL LINEAR FOOTPEDAL CONTROL US POWER LINEAR 30% (max) 80 PPS, 50% DC VACUUM RISE TIME – 2 US - 400 mmHg I/A - 600 mmHg

  5. MATERIALS & METHODS EVALUATION PARAMETERS: CORNEAL THICKNESS, INCISION LENGTH, ANGLE OF INCISION EVALUATION INTERVALS: 1 DAY, 1 WEEK, 2 WEEKS, 4 WEEKS POSTOP

  6. RESULTS CCI ARCHITECTURE

  7. RESULTS CORNEAL THICKNESS DYNAMICS

  8. RESULTS INCISION ANGLE vs CORNEAL THICKNESS CHANGES (1st day POSTOP)

  9. CONCLUSIONS • THERE IS NO SIGNIFICANT DIFFERENCE BETWEEN 1.8 mm and 2.8 mm GROUPS IN ENDOTHELIAL MISALIGNMENT AND DESCEMET MEMBRANE DEFECTS • THE PATTERN OF STROMAL HYDRATION IN POSTOPERATIVE PERIOD DIFFERS WITH THE SIZE OF THE INCISION • CORNEAL EDEMA AT THE 1ST POSTOP DAY IN 1.8 mm GROUP IS MORE SIGNIFICANT BUT IT’S RESOLUTION HAS A TENDENCY TO OCCUR EARLIER THAN IN 2.8 mm GROUP • INCISIONS WITH SHARPER ANGLE OF ATTACK (19 vs 24 deg.) IN BOTH 1.8 mm and 2.8 mm GROUPS WERE FOLLOWED BY LESS STROMAL HYDRATION AND QUICKER CORNEAL THICKNESS RECOVERY
