Masaki Tanito
Trabeculotomy (LOT) is performed to reduce the intraocular pressure in patients with glaucoma, both in children and adults. It relieves the resistance to aqueous flow by cleaving the trabecular meshwork and the inner walls of Schlemm's canal. Microhook ab interno LOT (µLOT), a novel minimally invasive glaucoma surgery, incises trabecular meshwork using small hooks that are inserted through corneal side ports. An initial case series reported that both µLOT alone and combination of µLOT and cataract surgery normalize the intraocular pressure during the early postoperative period in Japanese patients with glaucoma...

Konstantinos Laios
Professor Samuel David Gross (1805-1884) is considered as one of the founders of American surgery. He was a skillful surgeon who could excellently perform a lithotomy, an amputation, and a cataract surgery. He introduced many new surgical techniques and designed new surgical and medical instruments. He expertise was not limited to surgery alone; he also published studies concerning internal medicine, pathology, experimental physiology, and pharmacology. His most important treatise was his 2-volume work, A System of Surgery, Pathological, Diagnostic, Therapeutic and Operative (1861), which was a standard reference book in surgery in the United States during the second half of 19th century...

Juris Vanags, Renārs Erts, Guna Laganovska
BACKGROUND AND OBJECTIVE: This study sought to evaluate anterior capsulorhexis opening (ACO) reductions after surgery for a subluxated lens. Significant reduction of an ACO supports direct zonular involvement (capsular factors excluded by use of capsular tension rings [CTRs] and modern intraocular lens [IOLs]), and these findings question the long-term efficacy of subluxated lens surgery by means of cataract surgery. A small ACO due to lens mobility, non-enlargement of the ACO, and no lens epithelial cell washing due to an additional risk of further zonular damage were left as additional features to evaluate the possible outcomes of this simplified but still complicated surgery...

We present two cases with focal corneal edema due to Fuchs' endothelial dystrophy that were successfully treated with mini Descemet membrane stripping (m-DMES) (diameter of 3-4 mm; at the area of preexisting focal corneal edema) without endothelial replacement during cataract surgery. Specular microscopy demonstrated Fuchs' endothelial dystrophy and histopathologic evaluation confirmed the diagnosis. Anterior segment optical coherence tomography and confocal microscopy were used for the evaluation of the corneal tissue recovery course after the surgical procedure...

Posterior polar cataracts (PPC) have always been a challenge for cataract surgeons due to their inherently higher propensity for posterior capsule rupture. Over the years, several technical modifications have been suggested to enhance safety and reduce posterior capsule rupture rates in these polar cataracts. This review article tries to present the various techniques and strategies to published in literature to manage PPCs. It also discusses pearls for making surgery more reproducible and consistent, as well as the role of newer diagnostic and surgical technology based on the published literature on the subject...

The visual outcome of uveitic cataract surgery depends on the underlying uveitic diagnosis, the presence of vision-limiting pathology and perioperative optimization of disease control. A comprehensive preoperative ophthalmic assessment for the presence of concomitant ocular pathology, with particular emphasis on macula and optic nerve involvement, is essential to determine which patients will benefit from improved vision after cataract surgery. Meticulous examination in conjunction with adjunct investigations can help in preoperative surgical planning and in determining the need for combined or staged procedures...

Michael Lawless, Lewis Levitz, Chris Hodge
Femtosecond laser-assisted cataract surgery (FLACS) was introduced in 2009 and has increasingly been incorporated into surgical practice. The automation of three key aspects of cataract surgery was expected to deliver a significant improvement in both refractive and safety outcomes. The published literature has not yet shown consistent refractive improvement above conventional techniques. The purpose of this paper is to review current FLACS refractive outcomes and explore factors that may have contributed to the current findings and whether future improvements are possible...

REVIEW
Aazim A Siddiqui, Uday Devgan
Cataract surgery is the most performed surgical procedure in the field of ophthalmology. The process of intraocular lens (IOL) calculations is a critical step to achieving successful outcomes. Many IOL formulae exist to guide surgeons through the difficult process of picking the most appropriate lens to achieve a certain target refraction. However, these formulae reach within 0.50 diopters of the target refraction only 75% of the time, leaving 25% of the eyes with a significant refractive surprise. A literature review was performed to investigate all the relevant published material on the history, progress, and recent advancements of IOL calculations...

The manual extracapsular extraction of the lens is the surgical technique that is most practiced for the treatment of cataract in sub-Saharan Africa. Learning this technique requires the creation of a surgical simulation unit within training institutes. We describe the development stages of a traditional simulation unit. For this purpose, we present a description of four steps involved in the development of a simulation unit for cataract surgery: the physical creation of the room, the aseptic and antisepsis conditions, the management of the eyes, the development of a curriculum and the administrative policies...

Implantation of artificial intraocular lenses (IOL) after cataract removal today represents the standard of care in the field of anterior segment surgery. In refractive lens exchange cases the natural lens is replaced by an IOL to correct different types of refractive situations. In the majority of the operations the refractive result is satisfying with only few deviations from target refraction.But daily practice reveals some outliers from the intended corrections with the need for further refractive enhancements, respectively...

Posterior keratoconus (PKC) is a rare, typically non-inflammatory condition that is characterised by an abnormal posterior corneal curvature, which may be accompanied by overlying stromal opacification. It is usually congenital and can be associated with other ocular and systemic abnormalities. PKC remains a clinical diagnosis, although imaging techniques including ultrasound biomicroscopy and anterior segment optical coherence tomography may be useful tools for confirmation and classification. Genetic studies should be considered, although no specific genetic defects have been identified thus far...
