Three-Port MICS (Tri-MICS): Experimental Studies and Clinical
Aspects

Purpose: To describe the concept, experimental studies and clinical results of
the Tri-MICS technique.
Methods: Phacoemulsification was done in experimental and clinical settings
using a separate irrigation line as the sole fluid source throughout surgery,
including all pre- and post- phaco maneuvers and IOL implantation. Temperature
around the phaco tip was measured using infra-red thermal camera.
Results: Most commercially available anterior chamber maintainers (20G) do
not provide sufficient flow and a larger tubing (19G) is required. Surgery can be
safely performed using a variety of phaco machines. The additional (third) stab
incision has no effect on corneal astigmatism. The naked phaco tip does not
cause corneal burns because of constant cooling by the leaking fluid.
Conclusions: Separating the 3 functions required for phaco surgery (metal tip,
second-hand instrument and irrigation line) increases safety and efficacy of
micro incisional (1.1 mm) phacoemulsfication.

Advantages of IOL Implantation in Ringer Lactate
(Hydroimplantation) Without Using Visco-Elastic Substance in Small
Incision Cataract Surgery (SICS)

Purpose: To study the advantages of using ringer lactate instead of viscoelastic
substance for implantation of intraocular lenses in SICS.
Material and Methods: It was a prospective, randomized, interventional study
of 100 patients. Outcome measure- safety, efficacy, post-operative IOP, postop
AC reaction, endothelial cell count, surgical time.
Results: There were no intra operative complications. The mean post operative
IOP at 6, 24 and 48 hrs in ringer group was 16.02, 13.46 and12.44 mmHg
and in visco group 22.24, 17.32 and 13.84 mmHg respectively. Difference was
significant (p value .05) not significant. Mean endothelial cell
loss difference was not significant (p value 0.055).
Conclusion: Only a small modification in one step of SICS can significantly
control spikes of IOP with significantly lesser post operative reaction. With
some experience, implantation of IOL in the bag under a continuous irrigation
of Ringer Lactate is safe, accurate and less time consuming method without
any significant extra loss of endothelial cells.

Optical and Functional Results After Implantation of Multifokal Lentis
M Plus

Purpose: To evaluate the optical, functional outcomes, contrast sensitivity and
patients satisfaction after Implantation of multifocal LENTIS IOL (Oculentis),
with features of a completely new approach in multifocal lens technology.
Methods: In a prospective case study from November 2009 until February 2011
we implanted LENTIS Mplus in 52 eyes of 34 patients bilateral and monolateral.
The mean age was 69 years. We evaluated pre and post-operative refraction,
uncorrected (UCVA), distance and, intermediate and near visual acuity. The
quality of vision and the personal satisfaction of the patients were assessed
with a validated questionnaire.
Results: Three months after the Implantation the mean UCVA the BCDVA
preoperatively was 0,35log Mar, postoperatively 0,15log Mar. The mean SEQ
was +1, 02 preoperatively,-0, 23 three months after the operation. The mean
UCVA for distance tree months postoperatively was 0, 24 log Mar, 0, 34 logMar
for intermediate and 0,28 logMar for near vision. 45% were satisfied, 25% were
moderate satisfied. Only 22% patients needed glasses for reading of small
print, nobody for the working on PC. All patients were satisfied with achieved
visual acuity during the car driving during the day, 50% even satisfied during
the night.
Conclusion: The Results after implantation of MF IOL Lentis M plus are very
promising.

Push Pull Phaco Prechop: Intraoperative Safety and Efficacy
Mathen Minu (1)
1. Chaithanya Eye Hospital
Purpose: To evaluate the safety and efficacy of a new technique push pull
phaco prechop (PPPP) and to compare it with the phaco chop technique.
Methods: Prospective study including 76 patients (cataracts less than grade 3)
randomized into two groups (38 each) to compare push pull phaco prechop
(PPPP)( group I ) and conventional phaco chop (Group II) techniques. All
surgeries (same surgeon) were uncomplicated.
Results: Comparing group I and II, the average duration of surgery was 749.92
+ 54.21 seconds vs. 808.47 + 66.36 seconds (p< 0.001), average Effect Phaco
Time ( in seconds) was 2.28+ 0.72 vs. 4.14+ 0.88 (p
