PURPOSE To characterize the early ocular-surface changes or tear inflammatory-mediators levels following small-incision lenticule extraction (ReLEx smile) and femtosecond laser-assisted laser in situ keratomileusis (FS-LASIK). METHODS Forty-seven myopic subjects were recruited for this prospective study. Fifteen underwent ReLEx smile and thirty-two underwent FS-LASIK. Corneal fluorescein (FL)...

We evaluated the feasibility and safety of nictitating membrane fixation to address reduced contact lens stability by the nictitating membrane in a rabbit model. Under general anesthesia, twelve animals received a horizontal mattress suture between the nictitating membrane and the upper eyelid of one eye. To assess the effects of this technique and secondary side effects, contact lens stability...

Objectives. To evaluate the effects of microincision cataract surgery on dry eye-associated symptoms and signs. Methods. This prospective study included 40 eyes of 32 patients. Microincision cataract surgery was performed to eyes through 2.2 mm superior clear corneal incision. Dry eye-associated symptom scoring, corneal sensitivity test, Schirmer 1 test, tear break-up time (tBUT) were measured ...

PURPOSE Diabetes mellitus is an increasingly common systemic disease. Many diabetic patients seek cataract surgery for a better visual acuity. Unlike in the general population, the influence of cataract surgery on tear film function in diabetic patients remains elusive. The aim of this study was to evaluate the tear function in diabetic and nondiabetic patients following cataract surgery. MET...

Abstract This paper attempts to re-investigate the catching-up (stochastic convergence) hypothesis among the selected 16 OECD countries applying the time series approach of convergence hypothesis with annual data over one century. To reach this aim, we propose a model which specifies a trend function, incorporating both types of structural breaks – that is, sharp breaks and smooth shifts usin...

Dry eye disease (DED) is a multifactorial that represents one of the most common ophthalmologic conditions encountered in everyday clinical practice. Traditional diagnostic tests for DED, such as subjective questionnaires, tear film break-up time and Schirmer test, are often associated with poor reproducibility reliability, which make diagnosis, follow-up, management challenging. New advances i...

Purpose: This study compared the clinical parameters and histological findings according to benzalkonium chloride concentration (BAC; 0.05%, 0.1%, 0.2%) for inducing experimental dry eye (EDE) in a rabbit model.Methods: Rabbits were divided into four groups BAC concentration: untreated group, 0.2% BAC. was instilled topically both eyes of rabbits twice daily until they euthanized after 14 days....
