Purpose: To evaluate the efficacy of staining of posterior capsule with trypan
blue during capsulorhexis in cases of pediatric cataract.
Patients and Methods: In a prospective study, two groups of children with
pediatric cataract randomly allocated to undergo cataract extraction. In
group A (11 eyes), trypan blue was used to stain the posterior capsule during
the posterior capsulorhexis. Group B (10 eyes) were done without staining
of posterior capsule. The two groups were compared for completion of the
capsulorhexis, and IOL implantation (in sulcus or in the bag).
Results: The study included 21 eyes of 16 patients (age range: 6 months – 4
years). There is significant statistically difference between two groups
in capsulorhexis completion (p= 0.04), intra-bagal intraocular lens (IOL)
implantation (p = 0.022), the incidence of postoperative posterior capsule
opacification (PCO) (0.01).
Conclusion: This study suggests that staining of posterior capsule during
capsulorhexis in pediatric cataract operation gives better results than
capsulorhexis without staining. The stain changes the capsule texture making
the capsulorhexis easier with less complications.

Objective: To evaluate surgically induced astigmatism (SIA), torque and
flattening effect following phacoemulsification with 3.2, 2.2 and 1.8-mm
superior clear corneal incisions.
Methods: Prospective non randomized series of 192 eyes (61 eyes with a 3.2mm
incision, 68 eyes with a 2.2-mm incision and 63 eyes with a 1.8-mm
incision). Alpins vector analysis was used to calculate SIA, torque and
flattening effect 1 month postoperatively. Results: Superior 3.2-mm corneal
incisions showed statistically significantly greater SIA compared to 2.2 and
1.8-mm incisions (0.99 ± 0.07 v 0.63 ± 0.05 v 0.51 ± 0.04). The comparison of
2.2 v 1.8-mm incisions was also statistically significant in terms of SIA, but the
two incisions were similar in terms of torque (0.35 ± 0.04 v 0.29 ± 0.03 [p: 0.55])
and flattening effect (0.43 ± 0.06 v 0.33 ± 0.04 [p: 0.23]).
Conclusion: Standard 3.2-mm corneal incisions produced more SIA and
flattening effect compared to 2.2 and 1.8-mm incisions. The comparison of 2.2
and 1.8-mm incisions showed a significant difference for the SIA only.

Course Objective: Attendees will discuss how complications happened. A
detail discussion on identification of sequence of events leading to the
complications and how they could be avoided for better end results and good
patient satisfaction for better visual outcome.
Course Summary: Course will describe how simple cases go into disasters in
Phaco. It is an advanced video Instruction Course in which difficult situations
like Chemosis, a typical surge at the last piece, Nucleus drop, Re-gluing the
sublaxated IOL, sublaxation of IOLs, Zonular dialysis, Anterior capsular flap
complication, Instrument hook induced complications, Incision going wrong
and ccc going radial, Microphaco gone tough and many more are shown. The
course will also cover the unsteady Capsular Bag.
Target Audience: General ophthalmologists (anterior segment surgeons).

Objective: To highlight various modifications associated with trabeculectomy
and their outcomes
Summary of Content: Trabeculectomy, the guarded filteration surgery, has
been a gold standard in glaucoma surgery for the last 5-6 decades. If
performed properly it helps to lower intraocular pressure without any adverse
effects. Complications of trabeculectomy occur even in the hands of the
expert. To enhance success rates additional modifications are in vogue.
These modifications have not caught on uniformly amongst the practicing
ophthalmologist. In this video instruction course we describe the various
modifications (preparation and use of cytocidal and cytotoxic antimetabolites,
type 2 ologen collagen matrix implant, various releasable suture techniques
and the newer express shunt) along with tips for safe surgery for optimal
outcome of trabeculectomy.
Target Audience: Practicing ophthalmologist, residents
