INSERTED
TWO LAMELLAR SCLERAL
FLAPS 180 DEGREES
APART WERE MADE
A
SCLERAL FLAPS
SCLEROTOMY WAS MADE
UNDER EACH FLAP 1 MM
FROM THE LIMBUS
THE IOL HAPTIC WAS
GRASPED WITH 23 G MST
FORCEPS AND
EXTERIORIZED UNDER
THE FLAP
BOTH HAPTIC TIPS WERE
TUCKED INTO SCLERAL
TUNNELS AT THE EDGE OF
THE FLAPS
FIBRIN GLUE WAS USED TO
SEAL THE FLAP

ULTRASOUND BIOMICROSCOPY USED
LINE WAS DRAWN ALONG LIMBUS AS PLANE OF
REFERENCE
SECOND LINEWAS DRAWN ALONG LONG AXIS OF
IOL OPTIC
OPTIC WAS CONSIDERED NOT TILTED WHEN
REFERENCE LINE ALONG LIMBUS AND IOL OPTIC
WERE PARALLEL
ACCORDING TO EQUATION OF STRAIGHT LINE, Y
= MX + C, SLOPE OF LINE THROUGH LIMBUS AND
IOL WAS DETERMINED
SLOPES WERE CALCULATED AS
M = (Y2-Y1)/(X2-X1)
WHERE (X1, Y1) & (X2, Y2) ARE ANY TWO
POINTS ON THE 2 LINES.
IF TWO STRAIGHT LINES ARE PARALLEL,
THERE SLOPES WILL BE
EQUAL; OR THE RATIO WILL BE 1.
RATIO BETWEEN SLOPE OF LINE 1 & LINE 2
WAS CALCULATED
ABSOLUTE MEAN SLOPE OF LINE (L1) THROUGH LIMBUS =
0.032 ± 0.09
ABSOLUTE MEAN SLOPE OF LINE (L2) THROUGH IOL OPTIC =
MEAN RATIO OF SLOPE = 1.04 ± 0.28

•MEAN X AND Y SHIFT

RESPECTIVELY.
DECENTRATION OF THE GEOMETRIC
CENTER OF THE IOL OPTIC (a1) WITH
RESPECT TO LIMBUS (a) WAS DETERMINED
AS r (MM)
MILD DECENTERATION DETECTED IN
AN EYE IN EARLY POST OPERATIVE
PERIOD
•SERIAL DIGITAL SLIT LAMP IMAGES OF THE EYE WITH FULL PUPILLARY DILATATION
WERE TAKEN TO ASSESS IOLCENTERATION
•IMAGE PROCESSING WITH MATLAB VERSION 7.1 (MATHWORKS, INC) WAS DONE TO
QUANTIFY DECENTERATION
•GEOMETRIC CENTRE OF THE LIMBUS (a) AND THE IOL OPTIC (a1) WAS DEDUCTED AFTER
COMPLETE PUPILLARY DILATATION
•DISTANCE (r) BETWEEN THE TWO GEOMETRIC POINTS WERE CALCULATED IN MM ON
EACH VISIT
•AMOUNT OF DECENTRATION OF THE GEOMETRIC CENTER OF THE IOL OPTIC WITH
RESPECT TO THE X-AXIS AND Y-AXIS OF A 2-DIMENSIONAL CARTESIAN SYSTEM (THE
CORONAL PLANE) WAS DETERMINED
