Purpose: To assess the effects of phacoemulsification cataract surgery (PCS) and its pharmacological support on the prevalence of dry eye (DE) type ocular surface changes.
Material And Methods: The study included 550 patients with age-related (369 patients) or complicated (181 patients) cataracts (247 men, 303 women; mean age 71.6±7.3 years) who were assessed using the Ocular Surface Disease Index (OSDI), tear break-up test (TBUT), Shirmer-1 test, lipid interference test, OCT meniscometry, examined for xerosis indicators and «lid vipers» symptom in order to detect DE before PCS, as well as on days 1, 7, 30 after PCS. Meibomian gland dysfunction (MGD) was determined by the Norn compression test, which was performed before PCS. The significance of differences was assessed using Pearson χ test.
Results: Before PCS the prevalence of DE was 51.1%, asymptomatic subclinical DE - 28.9%. MGD was detected in 79.4% of DE patients and in 50.3% subclinical DE patients. After PCS, an increase in DE prevalence was noted (due to increase in the prevalence of mild DE): on the 1 day - up to 58% (χ=5.295; =0.022; <0.05), on the 7 day after surgery - up to 63.1% (χ=16.165; =0.001; <0.01), on the 30 day - up to 55.6% (χ=2.283; =0.131; >0.05).
Conclusion: The study revealed a trend towards an increase in DE prevalence after PCS (due to an increase in the proportion of hypersecretory mild DE), which was statistically significant on days 1 and 7 after the operation and statistically insignificant by the 30 day after surgery. Apparently, it could be associated with aggravation of "background" asymptomatic ocular surface changes. From our point of view, the high prevalence of DE and subclinical DE in cataract patients before PCS makes it advisable to carry out preoperative preparation aimed at normalizing the condition of ocular surface. At the same time, the high prevalence of MGD in DE and subclinical DE patients determines one of the directions of preoperative treatment - eyelids hygiene.

Contact lenses have become integral tools in the realm of ocular therapeutics, extending beyond their primary function of refractive correction to encompass a diverse array of therapeutic applications. This review explores the evolving role of contact lenses in managing various ocular conditions, highlighting their efficacy in enhancing patient outcomes. Initially developed to correct refractive errors, contact lenses now serve as effective vehicles for delivering medications directly to the ocular surface, offering targeted treatment for conditions such as dry eye syndrome and corneal ulcers.

Backround: Prednisolone-Derived Corticosteroid (PDC), has anti-inflammatory activity in ocular administration. However, drug administration to the eye is extremely difficult due to the complex structure of the eye. Because of the ability of the eye to retain the drug and its physiology, the bioavailability of drugs applied to the eye is very low.

Introduction: Ocular pain is a common complaint to eye care providers, associated with a variety of ocular conditions, among which dry eye disease (DED) is affecting millions of people worldwide. Despite being highly prevalent, ocular pain is not managed adequately in the clinic.
Objectives: The aim of this study was to investigate the analgesic potential of neurokinin-1 receptor (NK1R) antagonism in DED.

Purpose: This study highlights the feasibility of femtosecond laser-assisted large-diameter lamellar corneal-limbal keratoplasty and its efficacy in the treatment of ocular surface failure caused by bilateral ocular chemical injury.
Observations: The series included 3 patients with ocular surface failure caused by bilateral ocular chemical burns. After dissection of the host cornea, a femtosecond laser-assisted large-diameter lamellar corneoscleral button, with varying thickness of 250-400 μm, was sutured to the recipient bed.
