The Islamic culture flourished between the 9th and 13th centuries. Scholars from this era made significant contributions in mathematics, science and medicine. Caliphs and physicians built hospitals that provided universal care and the foundation for medical education. Physician-scientists made significant advances in medical care, surgery and pharmacology. Notable authorities include al-Razi (865-925 CE) who wrote the Kitab al-Hawi fi al-tibb (The Comprehensive Book on Medicine), a 23-volume textbook that provided the main medical curriculum for European schools into the 14th century...

PURPOSE OF REVIEW: Achieving secure wound closure in clear corneal incision cataract surgery remains highly desired for its role in reducing infection risk and leak-related complications, including hypotony, corneal edema, and lens dislocation. Although classic techniques of stromal hydration or wound suturing represent traditional approaches, the introduction of newer and more effective ocular surface adhesives has increased the options that are available. This review aims to provide an update on the peer-reviewed literature regarding wound closure and the currently available and investigational tissue adhesives used to seal clear corneal incisions in cataract surgery...

The performance of an intraocular lens is determined by several factors such as the surgical technique, surgical complications, intraocular lens biomaterial and design, and host reaction to the lens. The factor indicating the biocompatibility of an intraocular lens is the behavior of inflammatory and lens epithelial cells. Hence, the biocompatibility of intraocular lens materials is assessed in terms of uveal biocompatibility, based on the inflammatory foreign-body reaction of the eye against the implant, and in terms of capsular biocompatibility, determined by the relationship of the intraocular lens with residual lens epithelial cells within the capsular bag...

REVIEW

Pseudoexfoliation is a ubiquitous syndrome of multifactorial origin affecting elderly people by increasing the risk of cataract and secondary glaucoma development. Despite modern techniques and technologies for cataract surgery, pseudoexfoliation syndrome represents a challenge for surgeons because of the increased weakness of the zonular apparatus and limited pupil dilation. Due to the inherent difficulties during surgery, the risk of vitreous loss in these patients is several times higher than in cataract patients without pseudoexfoliation...

Presbyopia and cataract patients' desire for increased spectacle independence after surgery is one of the main drivers for the development of multifocal intraocular lenses (MIOLs) and extended depth of focus (EDOF) intraocular lenses (IOLs). As education, biometry, diagnostics, surgical techniques, and MIOL/EDOF IOL designs have improved over the past decade, an increasing number of cataract surgeons have become cataract-refractive surgeons to help address this need. There is not 1 single MIOL/EDOF IOL, however, that suits all patients' needs...

CASE REPORT: A 78-year-old woman with rheumatoid arthritis and secondary Sjögren's syndrome presented with corneal melting three days after cataract extraction that required penetrating keratoplasty. By the fourth month, a second corneal transplant was needed due to a new descemetocele associated with her systemic disease. DISCUSSION: The underlying disease, together with the surgical history, was responsible for the complication presented. The correct anamnesis prior to cataract surgery, a refined technique, and a close post-operative follow-up can avoid such a serious complication...

Dry eye can be caused by a variety of iatrogenic interventions. The increasing number of patients looking for eye care or cosmetic procedures involving the eyes, together with a better understanding of the pathophysiological mechanisms of dry eye disease (DED), have led to the need of a specific report about iatrogenic dry eye within the TFOS DEWS II. Topical medications can cause DED due to their allergic, toxic and immuno-inflammatory effects on the ocular surface. Preservatives, such as benzalkonium chloride, may further aggravate DED...

Endothelial keratoplasty (EK) has revolutionized corneal transplant surgery by providing rapid visual recovery and improved visual outcomes. In parts of the world with Fuchs endothelial dystrophy, many patients may present with both cataracts and corneal degeneration requiring surgery. Other forms of endothelial decompensation may also present with cataracts. The staging or combination of transplant surgery and cataract surgery depend on both the abilities of the surgeon and the surgical techniques being considered...

Jinfei Tang, Ergang Du, Jie Wang
RATIONALE: Cyclodialysis cleft is a relatively rare but severe condition with persistent ocular hypotony, which can cause morphologic changes and visual loss. Here we report a case of a traumatic cyclodialysis cleft that was successfully managed with direct cyclopexy via anterior chamber perfusion. During the operation, if there is aqueous humor flowing out of the deep scleral incision, the cleft is not closed, and surgery should continue until there is no aqueous outflow. PATIENT CONCERNS: A 66-year-old man was treated for severe blunt ocular trauma of the left eye and a resultant cyclodialysis cleft, lens subluxation, choroidal detachment and a cataract...

Malkit K Singh, Balamurali K Ambati, Alan S Crandall
We describe clinical applications and surgical techniques for a new type of capsular tension segment (CTS) for use during cataract surgery. The Ambati CTS is distinguished from other CTS devices by having 2 eyelets close to each other, which allows it to distribute tension to 2 points, avoiding too much stress at a single point on the anterior capsulotomy, which prevents peaking of the capsulorhexis, and potentially reducing the risk for anterior capsule tear. Two of these CTS devices could possibly be used to provide 4-point fixation of a capsular bag in eyes with near-complete zonular instability...
