Uso de viscoelásticos na facoemulsificação em cães portadores de catarata: efeitos sobre a pressão intraocular, a morfologia das células endoteliais e a espessura corneana

“…In the present study, no difference on uveitis manifestation was observed when both groups were compared. CHIURCIU et al (2010) reported a signifi cant decrease on endothelial cells density following phacoemulsifi cation in dogs. The same was not observed in the present study.…”

“…For the G2 patients (mature), the values differed at all times, with endothelial loss of 24% 60 days after phacoemulsification. The same was described by Chiurciu et al (2010) and Gwin Lerner, Warren, & Gum (1983) studying patients who underwent bimanual phacoemulsification (24.97%) and cataract surgery (22%), respectively. The corneal endothelium of dogs responds to surgical trauma similarly to that of humans, maintaining the functional monolayer with increased cell size and migration (Mencucci.…”

“…It begins immediately after trauma or exposure to allergens or toxins so was expected immediately after phacoemulsification (Munger, 2009). There were no postoperative complications identified such as fibrovascular membranes, growth of lenticular fibers, lenticular epithelial membranes, or endophthalmitis (Munger, 2009) It can be inferred that the presence of immature or mature cataracts does not influence the density values or cell area of the corneal endothelial cells, as the values obtained preoperatively did not differ between the groups and were not as described by Chiurciu et al (2010) and Pigatto et al (2006).…”

The aim of this study was to evaluate the feasibility of the V-Prechop nucleodissection technique in the phacoemulsification in dogs and the clinical aspects and of the specular microscopy in the postoperative period. Fourty three dogs of different breeds, males and females, aged 3 to 10 years, with mature (n=22) and immature (n=21) cataracts were used. After surgery, patients were evaluated weekly for visual acuity, intraocular pressure, and endothelial corneal cell density (by non-contact specular microscopy) and quantitative flare (by laser flare photometry) during different periods. The "V-prechop" technique presented technical difficulties in implementation in patients with a mature cataract. In selected cases of patients with an immature cataract, the technique can be employed, as the nuclei are softer, allowing confection of the linear fragments in “V” to be performed. In addition, the eyes of dogs with a mature cataract presented more intensive postoperative uveitis, probably related to the greater difficulty in conducting the "V" nucleodissection. There was decreased endothelial corneal cell density in dogs with mature and immature cataracts. This occurrence was greater in patients with a mature cataract, given the increased intraocular manipulation and surgical time due to the difficulty in performing the “V” nucleodissection. According to the results obtained, the “V-prechop” nucleodissection technique can be indicated in selective cases of dogs with an immature cataract.

The aim of this study was to analyze for 120 days, post-operative complications following bimanual phacoemulsification with implantation of hydrophilic or hydrophobic intraocular acrylic lens. The hospital records of 15 dogs were analyzed, and distributed in two groups, being Gfi and Gfo the hydrophilic intraocular lens and hydrophobic intraocular lens group, respectively. On the first day, both groups presented blepharospasm, conjunctival hyperemia and flare. On day 1, fibrin was slightly apparent in two and three eyes of Gfi and Gfo, and on day 7, present in one and two patients from Gfi and Gfo. Synechia was observed on day 1 in one eye from Gfi and Gfo. Two eyes from Gfi developed from 7 to 120 days, and in Gfo, one eye developed from 7 to 90 days, on day 120, two eyes formed them. The presence of posterior capsule opacity of the lens in all periods, there was no statistical significant between the groups. Only one eye, in Gfo, that had no opacity formation. The intraocular pressure of both groups remained within normal range. There was no statistical significance between hydrophilic and hydrophobic intraocular lens, the use of intraocular lens has led to satisfactory results in visual ability.
