ABSTRACT
Topical glaucoma therapy is a long termed, usually lifelong. Antiglaucomatous drugs have toxic effects on ocular surface, due to preservative toxicitiy or the drug itself. Adding a lubricant eyedrops to antiglaucomatous therapy, especially if considering the preservative used, can have protective effect. The purpose of this study was to evaluate the stabilty of precorneal tear film in glaucoma patient prior and after administration of lubricant eye drops with different tipe of preservatives. The study showed the protective role of ocular surface lubrication especially when using drugs with less harmful preservatives.

Refractory glaucoma in a complicated type of glaucoma of different ethyologies with one same characteristic--intraocular pressure of great resistance to therapy. There are different methods of treatment in such glaucomas, primary surgical options. Ex-PRESS miniature glaucoma shunt implantation was our treatment of choice. In our group of patients we achieved stabile intraocular pressure values in 4 month period of time with no serious or unexpected complications.

Postoperative refractive outcome largely depends on the accuracy of calculating power of implanted IOL. Lens power calculation can be done by conventional ultrasound biometry and partial coherence laser interferometry (IOL Master). The aim was to compare the accuracy of IOL power calculations using conventional ultrasound biometry and partial coherence laser interferometry.40 eyes were included in this prospective randomized trial. Twenty eyes underwent IOL master and 20 eyes had aplanation ultrasound biometry. There were included only eyes with age-related cataract and postoperative natural visual acuity (VA) 0.7. Visual acuity was performed 6 weeks after cataract surgery. After 6 weeks best natural visual acuity were 0.9 (± 0.1) in IOL-Master group and 0.85 (± 0.15) in ultrasound biometry. The postoperative mean absolute refractive error was 0.75 (± 0.5) D for ultrasound biometry and 0.50 (± 0.50) D for IOL-Master. Optical biometry with the IOL-Master proved to be slightly more accurate than ultrasound biometry for IOL power calculation.

Capsular tension ring (CTR) is endocapsular support device important during cataract surgery in eyes with weak zonular apparatus. It was presented our experience, advantages and limitations of CTR in phacoemulsification cataract surgery with damaged zonules. Phacoemulsification surgery was performed by clear corneal technique using topical anesthesia. Capsular ring was implanted to stabilize the capsular bag before implantation of intraocular lens. CTR has become increasingly important in the management of zonular weakness during cataract extraction. It lowers the incidence of capsule contraction, stabilizes the capsular bag and enhances IOL centration.

Glaucoma patients not responding to maximum medical therapy with coexistent cataract are candidates for combined cataract and glaucoma therapy. There are different therapy models. The choice of therapy depends on numerous patient and surgeon related factors. Ex-PRESS mini glaucoma shunt is a modified trabeculectomy and can be combined with cataract surgery when indicated. In this paper we presented our experience with this combined procedure. Our results showed good intraocular pressure control and visual acuity improvement, comparable to other therapy choices.
