Objective/Purpose: Now a days, all techniques of cataract extraction are being
modified to give minimal astigmatism. In the same race, conventional Extra
Capsular Cataract Extraction was improved to Manual Small Incision Cataract
Surgery (MSICS) and Phacoemulsification. But this resulted in the procedure
becoming expensive with use of high end machines. Eventually, for developing
countries like India, manual SICS was affordable and had encouraging results.
The present study was undertaken to compare astigmatism induced by
superior and temporal sections in manual SICS.
Methods; Eyes having a steeper vertical keratometry reading were assigned to
Superior MSICS group(1) whereas eyes with a steeper horizontal keratometry
reading were assigned to Temporal MSICS group(2). Eyes with no astigmatism
were randomly assigned to either of the two groups. Both the groups had 54
eyes each.
Result: Total of 108 eyes were operated. 54 However in group 2, only 35 eyes
out of 54 completed the follow up of 90 days. The mean Surgically Induced
Astigmatism (SIA) in group 1 was found to be 1.45 ± 0.7387 and in group 2 was
0.75± 0.4067. P value was < 0.001.
Conclusion: SICS with temporal approach provides better stabilization of
refraction with significantly less SIA.

The New Bifocal Prismatic IOL for Patients with Age-Related
Maculodegeneration (AMD) and Cataract

The new bifocal prismatic IOL was manufactured by Morcher Company
(Germany). When it is used without high-plus spectacles, normal pseudophakic
vision remains, but the induced prismatic effect moves the image in direction
of healthier retina. When the new IOL is used with high-plus spectacles,
the induced prismatic effect moves the 2.4x magnified image in direction of
healthier retina.
Purpose: To evaluate the results of the implantation of new IOL in patients with
dry AMD and cataract.
Methods: Patients were selected if they had bilateral macular pathologies with
visual acuity no more than 20/200, cataract no more than grade 2. The manual
small incision cataract surgery with implantation of the new bifocal prismatic
IOL was performed in eight eyes of eight patients having AMD. Preoperative
distance visual acuity, postoperative distance and near visual acuity, intra
operative complications and postoperative complications were recorded.
Results: The follow-up interval was 2 years. The mean postoperative distance
visual acuity at the end of 2 years was 0.1 as compared with 0.047 preoperative
values. The mean postoperative near visual acuity with high-plus spectacles
was 0.4.
Conclusions: The implantation of new bifocal prismatic IOL has shown good
results in patients with AMD.

Phacoemulsification Techniques for the Superobese Subject
Mansour Ahmad (1)

Purpose: Obesity is becoming the number one health problem in the developed
world. Superobese subjects have problems in transportation inside the hospital,
having intravenous access, have short thick neck prone for sleep apnea, have
gastrointestinal reflux prone for aspiration, as well as multitude of comorbidities
like diabetes mellitus, coronary artery disease, arthropathy. Operating on such
patients is a great challenge.
Methods: We describe a standing phacoemulsification technique (SPT) with
the patient in reverse Trendelenburg position (RTP) as a means of performing
surgery in superobese patients. Low magnification microscope and low
aspiration settings are essential part of the technique.
Results: The patients tolerated the surgery with good vital signs. RTP allowed
the unload of the diaphragm and increase pulmonary compliance (improve
oxygenation and ventilation). Vitreous pressure present on supine position was
decreased markedly. Still 2 of 9 eyes had posterior capsular rupture.
Conclusion: Positive vitreous pressure from short neck, excess abdominal
pressure on the diaphragm and thorax and hence elevated central venous
pressure in obesity can be decreased by this modified technique.

Posterior Capsule Opacification Rate of Two Different Hydrophobic
Single Picece PCIOL - One Year Results of a Prospective Study

Purpose: To evaluate the PCO rate after one year of hydrophobic single piece
IOL with 360° sharp edge SE (Z-Flex 877FAB, Medicontur, Hungary) vs.
interrupted SE (Acrysof SA60AT, Alcon, USA) a prospective intraindividual and
interindividual study was performed.
Method: Standard phacoemulsification with in-the-bag implantation were
performed in seventy eyes of 35 patients. In one eye a hydrophobic IOL with
360° SE and in the other eye a hydrophobic IOL with interrupted SE was
implanted. At 12 month postoperativ all eyes were controlled and a photo in
retroillumination was made to estimate the PCO.
Results: At the primary end point of this prospective study none of the eyes
already a capsulotomy was performed. In seven eyes with IOL with interrupted
SE IOL epithelial cell in growth at the optic-haptic-junction was noted but with
no need for capsulotomy at 12 months postoperatively and one eye required
capsulotomy. In eyes with 360° SE IOL no clinically relevant PCO inside the
optic was noted at 12 months postoperatively.
Conclusion: We found a tendency of in growth of lens epithelial cells at the
optic-haptic-junction and higher PCO rate in IOL with interrupted SE. As PCO
development is a continuous process, longer follow-up is recommended.
