A dropped nucleus is a dreaded complication in routine cataract surgery, and its management requires an intervention by a vitreoretinal surgeon.

Silicone oil-induced glaucoma is associated with raised IOP that is often unresponsive to a medical line of management. Removal of silicone oil from the eye has to be weighed against the repercussions of retaining it inside the eye.

Single-pass four-throw pupilloplasty is a timber hitch type of knot that is self-retaining and self-locking. The technique comprises a single pass with four throws taken around the loop that is withdrawn from the anterior chamber.

Dr. Sergio Canabrava proposes a novel sutureless scleral fixation technique, named four-flanged technique, inspired by Lewis scleral fixation and the Yamane technique, using a 5-0 polypropylene suture, in order to simplify and improve the safety of scleral fixation using single-piece non-foldable IOLs.

Traumatic ocular injuries are often debilitating and visually challenging. These injuries require utmost care and attention as they can have repercussions that can last for a lifetime. A thorough preoperative evaluation is often hindered due to either rupture of the globe or accompanied haziness of the media that prevents detailed intraocular evaluation.

Pinhole visual acuity assessment is an important form of preoperative examination performed in cases with higher-order refractive error that helps to apprise the surgeon and the patient of the best possible vision that can be achieved after intraocular surgery.

Various techniques have been described in peer-review literature for the repair of iridodialysis. The twofold technique combines non-appositional as well as single-pass four-throw pupilloplasty and works effectively in all cases of iridodialysis with varied degree of severity.

The technique of IOL scaffold for IOL exchange was previously described by us, wherein the faulty IOL is levitated from the capsular bag into the anterior chamber followed by placement of another corrective foldable IOL into the bag. This technique can also be performed for cases with posterior capsular defect.

Traumatic injuries often leave a devastating effect on the visual potential of patients for an entire lifetime. Tactful handling of these cases is necessary, and often multiple surgical approaches are necessary to optimize the visual output.

Pseudophakic bullous keratopathy is a consequence and an indicator of the sequelae of the intraoperative struggle during cataract surgery. These cases often necessitate an endothelial keratoplasty procedure, as it is essential to replace the damaged endothelial cells with a donor graft with a high cell count. DMEK, DSEK, DSAEK, DMAEK and PDEK are the various endothelial keratoplasty procedures employed by surgeons to replace the diseased endothelium of the recipient with that of the donor.
