1. Vasan Eye Care Hospitals
Purpose: To analyze and compare visual outcomes of unilateral diffractive
MIOL and bilateral diffractive MIOL implantation
Methods: Total of 80 patients was studied. 40 patients underwent bilateral
diffractive multifocal IOL implantation. The next 40 patients had monofocal IOL
implantation earlier and were dissatisfied and wanted spectacle freedom. They
had diffractive MIOL in other eye All patients had phacoemulsification with
diffractive MIOL. All patients were operated between January 2009 and January
2010. A same eye surgeon performed all surgeries. Follow up were done on
10,30 90,180 days. Unaided, aided distant and near acuities were tested.
Patients were asked about visual quality through a printed questionnaire.
Results: Out of 40 patients, who had bilateral diffractive IOL implantation, 30
patients highly satisfied. 6 patients just satisfied, 4 patients totally dissatisfied.
Of the 40 patients who had unilateral diffractive IOL implantation, 32 patients
spectacle dependency was greatly reduced. 8 patients continued using reading
glasses and were not satisfied.
Conclusion: Diffractive multifocal in one eye and monofocal in other eye gives
good visual outcome, comparable to those with bilateral implantation.

Sulcus Fixated Toric Intraocular Lens for Astigmatism Correction in
Pseudophakic Patients

Purpose: To describe results of sulcus placement of single-piece acrylic
intraocular lenses (IOL) for astigmatism correction in pseudophakic eyes.
Methods: Retrospective evaluation of 19 patients (20 eyes, 14 women and 5
men, mean age 56.7) who had implanted supplementary IOL (Sulcoflex
Toric, Rayner, UK). Mean follow-up was six months. The evaluation
included uncorrected and best-corrected visual acuity for distance vision,
autorefractometry, contrast sensitivity and rotational stability of toric lens.
Results: All patients showed visual acuity improvement. Mean postoperative
results of UCVA and BCVA was 0.81 and 0.92, respectively. Spectacle
independence for distance vision was achieved in 85% of patients. There
were observed: in three cases IOL rotation which needed reoperation, in two
cases sulcoflex rotate to different axes but resulting cylinder was tolerated
with spectacle correction, in one case pigment dispersion and in two cases
transient intraocular pressure elevation. No dysphotopsia and pupillary block
were observed.
Conclusion: Our study shows that the implantation of sulcoflex is an interesting
option for correction of moderate to high astigmatism and optimizing results
after cataract surgery. The 10 degree angulations and round haptics minimize
adverse effects of sulcus placement of this lens. The problem of rotational
stability needs to further investigation.

Clinical Outcome of Intraocular Lens Implantation with Capsular
Tension Ring/Segment in Subluxated Crystalline or Cataractous
Lenses in Various Age Groups
Shobaki Ahmad (1)
1. King Hussein Medical Center
Objectives: To determine the outcome of intraocular lens implantation using
capsular tension ring in subluxated crystalline or cataractous lenses in different
age group.
Methods: Sixteen eyes of 10 patients with subluxation of crystalline or
cataractous lenses between 90 degrees and 180 degrees underwent
phacoemulsification, capsular tension ring or segment and intraocular lens
implantation. Each patient was examined for preoperative and postoperative
refraction, implant centration, and zonular dehiscence.
Results: Age ranged between 5 to 50 years. Out of 16 eyes, four had traumatic
and 12 had spontaneous subluxation of crystalline or cataractous lens.
Phacoemulsification was successfully performed with capsular tension ring
implantation in the capsular bag. Intraoperative zonular dialysis occurred in
two eyes. Anterior vitrectomy was performed in seven eyes to manage vitreous
prolapse. Type of intraocular lens implanted was hydrophobic acrylic in all eyes.
Fifteen eyes had a best corrected visual acuity of 20/40 or better 6 months post
surgery. Nine eyes developed significant posterior capsular opacification.
Conclusion: Phacoaspiration with capsular tension ring implantation makes
capsular bag intraocular lens fixation possible in most of the eyes with
subluxated crystalline or cataractous lenses. Capsular tension segment is
preferable than ring in large zonular dialysis.

Effect of Size and Thickness of Posterior Polar Cataract on Surgical
Outcome in Small Incision Cataract Surgery

Aim: To correlate size and thickness of posterior polar cataract (PPC) with
incidence of posterior capsular rupture (PCR) in small incision cataract surgery
(SICS).
Methods: Prospective non randomized interventional cohort study. Size of PPC
was measured using slit lamp and thickness of PPC by Ultrasound
Biomicroscopy (UBM). All patients underwent SICS operated by single surgeon
without doing hydro dissection.
Results: 66 eyes of 66 patients were included. There were 7(10.6%) PCR in 66
eyes. As regards size of PPC, Group (a) size < 4 mm 39 (59.09%) eyes, there
was 1(2.56%) PCR and Group (b) size > 4 mm - 27(40.90%) eyes, there
were 6(22.23%) PCR (P = 0.0298). As regards thickness of PPC, Group (a)
thickness < 0.4 mm - 30(45.45%) eyes, there was no PCR (0%) and group
(b) thickness >0.4 mm - 36(54.55%) eyes, there were 7(19.44%) PCR (P =
0.0198).
Conclusion: Thickness of PPC (as determined by UBM) and its size are
significant predictors of PCR in Posterior Polar Cataract.
