We describe the essential steps in the successful phacoemulsification of the rock-hard, dense cataract. Appropriate and directed preoperative history, physical examination, and diagnostics allow the surgeon to select the best incision, anesthesia, and intended surgical technique for a given dense nuclear challenge. Hard nucleus-specific approaches for hydrodissection, pupil management, and zonular protection then allow the surgeon to approach the rock-hard nucleus with maximum safety. Dense nuclear dismantling options are then discussed in detail along with fluidic and power modulation considerations...

We describe the technique of second-wave hydrodissection (the first wave being the initial cortical cleaving hydrodissection) performed after the removal of the cataract nucleus in femtosecond laser-assisted cataract surgery. After femtosecond laser application, the cortex is typically found adhered to the anterior capsule. Under high magnification, a steady stream of a balanced salt solution is directed toward the anterior capsule using a hydrodissection cannula. Full cleavage of the remaining cortex is observed by noting the appearance of a dark inner circle by the capsulotomy edge once the balanced salt solution wave has separated the cortex from the capsule...

Alastair Stuart, Dan Z Reinstein, Ryan S Vida, Timothy J Archer, Glenn Carp
We describe a case of atypical diffuse lamellar keratitis (DLK) following small-incision lenticule extraction (SMILE). The patient presented with multiple focal white infiltrates 1 day after routine small-incision lenticule extraction surgery. An interface washout was performed, and the patient was managed with intensive topical steroids. Potential infectious keratitis was also investigated (by culture and Gram stain) and treated aggressively with steroids and antibiotics. The cultures were all negative with no growth, and the focal infiltrates gradually resolved, with no relapses at the 15-month postoperative follow-up and a faint 0...

The technique, feasibility, and results of a new 25-gauge trocar-anterior chamber maintainer (ACM) designed for maintaining intraoperative fluid infusion is described in this prospective interventional analysis. The 25-gauge trocar-ACM with an overall length of the trocar blade of 6.0 mm, cannula length of 4.0 mm, and the cannula tip beveled at 45 degrees to the base was designed and used in all the cases. The dimensions of the sclerotomy wound that comprised of the internal ostium, external ostium, wound length, and the time interval for wound apposition in the postoperative period was analyzed by spectral-domain anterior segment optical coherence tomography...
