Eye Care in Leprosy: Changing scenario in a decade
Producer: Sanjoy Chowdhury

The leprosy prevalence in the state of Jharkhand in India is 2%, 60% of whom have eye problems, some leprosy-related and some age-related. Resources are scanty, social stigma a curse. Access to healthcare services is negligible. We took eye care to their doorstep. Starting with surgery for cataract by ICCE, during this first decade of this century we provided all advanced care including phaco. Now they can beat the drum all along the road to home without assistance. This film is about their suffering and how a little extra effort can alleviate it.

Microincisional Surgery of Subluxed Lenses with the Modified Capsular Tension Ring
Producer: Boris E. Malyugin

To present the new Modified Cionni CTR (MC CTR) used in patients with congenital and acquired subluxation of crystalline lenses. The new MC CTR is designed specifically for micro incisional cataract surgery (MICS). The MC CTR proved to be safe and provided favorable functional results. Surgical technique with the new device as well as the challenges is discussed. Financial disclosure: nothing to disclose.

Inamura Multi-Purpose Cannula
Producer: Inamura Mikio

This video will demonstrate a newly designed cannula which is useful in various aspects of cataract surgery. The cannula has two holes at the tip with some distance between them. This distance is adjusted to create a 30 degree angle between two spurts of water projected from the cannula. This cannula can be put to both irrigation and aspiration use. Irrigation uses are for hydrodissection and cleaning the operative field. Aspiration uses are for aspirating air bubbles in the anterior chamber, aspirating liquefied cortex in mature cataract cases, and repositioning the prolapsed iris in intraoperative floppy iris syndrome. These aspects will be shown in this video. The author has no financial interest in this product.

The Broken Capsule
Producer: Mohan Rajan
Co-producer: Sujatha Mohan

The video will highlight the most important complications of phacoemulsification, i.e., posterior capsule rupture (PCR). It will emphasize the importance of recognition, prevention and management of PCR, and various vitrectomy techniques. The video will also highlight the bailout options in the presence of PCR.

The Saviour
Producer: Srinivas K. Rao
Co-producer: Mohan Rajan

A scleral-fixated IOL offers cataract surgeons an important bailout option, when capsulo-zonular support is totally absent or inadequate. The video highlights the pearls and variations of scleral fixation of IOLS in these situations.

Simultaneous Surgery of DSAEK and Cataract
Producer: Kimiya Shimizu

In this presentation, I will show the difficult case of DSAEK with cataract surgery. First case: Bullous Keratopathy, 10 years after ACL implantation. In this case, we simultaneously perform DSAEK, AC IOL extraction, and phakic IOL fixed at sulcus ciliary muscle. Second case: Bullous Keratopathy after PACG attack. In this case we perform ECCE, phakic IOL implantation, and DSAEK.

Surgical Management of Dislocated Intraocular Lens (IOL) in a Double IOL System
Producer: Claudine E. Pang
Co-producer: Doric Wong

Purpose: To describe the dislocation of an IOL as a complication of a double IOL system and to illustrate the surgical removal of the dislocated IOL.

Setting: Singapore National Eye Centre, Singapore

Methods: Two unusual case reports of a double IOL system in which one IOL was posteriorly dislocated and surgical removal was indicated.

Results: In case 1, a patient with a double PCIOL system developed disclocation of the posterior IOL and an epiretinal membrane. In case 2, a post-penetrating keratoplasty patient with both a PCIOL and ACIOL developed dislocation of the PCIOL. Both patients underwent surgical removal of the dislocated IOL via a trans-scleral approach, assisted with a 23-gauge trans pars plana vitrectomy.

Conclusion: Dislocation of an IOL in a double IOL system may be managed by surgical removal via a trans-scleral approach, assisted with a 23-gauge trans pars plana vitrectomy.

Cataract Surgery in Patient with Totally Damaged Zonules: What is your choice?
Producer: Choun Ki Joo
Co-producers: Kyong Jin Cho, Yong Soo Byun

The case (41-year-old female) presented with decrease of vision in both eyes. Slit lamp examination revealed subluxation of lens in both eyes. He had no known systemic disease. Ocular manifestation included high myopia (axial length 31.46/30.82 mm). But, under surgical microscopy, the zonules were totally damaged and lens sank vertically onto the anterior vitreous in the left eye. Viscoelastic agent was injected quickly behind the nucleus. Capsulorhexis was done using internal limiting membrane peeling forceps, holding the lens with the IOL rotator because it moved freely. The capsular bag was stabilized with an iris retractor at seven sites and irrigation was done after aspiration during phacoemulsification. Then, the capsular bag was removed through the 2.2-mm clear corneal incision site. IOL implantation was not necessary for severe high myopia. Postoperative visual acuity without correction was 0.25 and a specific complication was not found.

Pupilloplasty and Intraocular Lens Implantation for Pupil Abnormality with Aphakia or Cataract
Producer: Haike Guo

Purpose: To evaluate the therapeutic effects and surgical techniques of pupilloplasty and intraocular lens implantation for 27 cases (29 eyes) with pupil abnormality and aphakia or cataract.

Methods: In this retrospective study, 29 eyes of 27 patients with pupil abnormality and aphakia, lens dislocation or cataract accepted pupilloplasty and intraocular lens implantation. Complications and visual acuity postoperatively were assessed. The follow-up was 7.8 months.

Results: Visual acuity improved in 25 of 29 eyes. 24 eyes have nearly round shaped pupil and normal pupil position. Vitreous hemorrhage occurred in one eye and hyphema occurred in three eyes. Three eyes developed high IOP.

Conclusions: Pupilloplasty combined intraocular lens implantation is a kind of effective technique for recovering vision and photophobia as far as possible. The key of surgical technique is to accurately evaluate the iris elasticity and stretchability preoperatively, choosing the way of lens implantation according to ocular condition.

Posterior Polar Cataract Phacoemulsification: Approach defying convention
Producer: Rohit O. Parkash

The author has been using physics principles as basis for managing posterior polar cataracts. The groundbreaking technique involves modified hydrodissection, no hydrodelineation and modified rotation in the slow motion technique of phacoemulsification. The surprisingly low posterior capsular rupture rate vindicates the author’s belief that posterior polar cataract needs a fresh look by all phacosurgeons.
