Deep anterior lamellar keratoplasty (DALK) is an emerging surgical technique for the restoration of corneal clarity and vision acuity. The big-bubble technique in DALK surgery is the most essential procedure that includes the air injection through a thin syringe needle to separate the dysfunctional region of the cornea. Even though DALK is a well-known transplant method, it is still challenged to manipulate the needle inside the cornea under the surgical microscope, which varies its surgical yield. Here, we introduce the DALK protocol based on the position-guided needle and M-mode optical coherence tomography (OCT)...

Reconstruction of the eyelids after skin cancer excision can be challenging. Surgical treatment options are multiple; deep anatomy knowledge of lamellar components is mandatory to choose the most adequate surgical planning. Eyelids' role in vision and social relationship is critical; both function and aesthetics are tough to restore. Using a flap provides a satisfying texture and colour match with adjacent tissues and ensures short contraction during healing; furthermore, grafts are sometimes necessary to achieve pleasing results...

A promising alternative for the next-generation lithography is based on the directed self-assembly of block copolymers (BCPs) used as a bottom-up tool for the definition of nanometric features. Herein, a straightforward integration flow for line-space patterning is reported for a silicon BCP system, that is, poly(1,1-dimethylsilacyclobutane)-b-poly(styrene) (PDMSB-b-PS), able to define sub 15 nm features. Both in-plane cylindrical (L0 = 20.7 nm) and out-of-plane lamellar structures (L0 = 23.2 nm) formed through a rapid thermal annealing-10 min at 180 °C-were successfully integrated using graphoepitaxy to provide a long-range ordering of the BCP structure without the use of underlayers or top coats...

Prashant Garg, Paavan Kalra, Joveeta Joseph
The purpose of the study is to describe epidemiology, clinical features, diagnosis, and treatment of Acanthamoeba keratitis (AK) with special focus on the disease in nonusers of contact lenses (CLs). This study was a perspective based on authors' experience and review of published literature. AK accounts for 2% of microbiology-proven cases of keratitis. Trauma and exposure to contaminated water are the main predisposing factors for the disease. Association with CLs is seen only in small fraction of cases. Contrary to classical description experience in India suggests that out of proportion pain, ring infiltrate, and radial keratoneuritis are seen in less than a third of cases...

This report describes the macroperforation of descemet's membrane (DM) during irrigation of the interface following successful removal of stromal tissue in big bubble (BB) deep anterior lamellar keratoplasty (DALK). A 42-year-old woman with keratoconus underwent a BB DALK procedure. After successful formation of Type 2 bubble and removal of stromal tissue, interface irrigation was performed to remove residual viscoelastic. This led to a macroperforation of DM, and the case was converted to penetrating keratoplasty...

A 38-year-old woman with advanced keratoconus initially developed Urrets-Zavalia Syndrome (UZS) in the left eye after deep anterior lamellar keratoplasty. During the uneventful surgery, a 7-mm-wide pupil unresponsive to light was noticed. On the first postoperative day, intraocular pressure (IOP) was elevated up to 45 mmHg with shallow anterior chamber (AC). A peripheral iridotomy in 2 o'clock position was conducted and a fixed combination of brinzolamide 1% and timolol 0.5% was administered topically. In the subsequent postoperative period, IOP was successfully reduced, but the patient reported severe photophobia, glare, and decreased vision...
