Оценить изменения кератометрических параметров после трех типов гипотензивных операций: синустрабекулэктомии (СТЭ), имплантации шунта Ex-PRESS и клапана Ahmed.</p></sec><sec><title>МЕТОДЫ</title><p>МЕТОДЫ. Исследуемую группу составили 196 пациентов, разделенных на три подгруппы: 1-я — пациенты, которым выполнена СТЭ (n=116); 2-я — пациенты после установки шунта Ex-PRESS (n=28); 3-я — пациенты, перенесшие имплантацию клапана Ahmed (n=52). Всем обследуемым до операции, а также через 30 дней и 6 месяцев после вмешательства выполнялись кератометрия (Topcon-8800) и кератотопография (Tomey RT-7000) для визуализации роговичного астигматизма (РА).</p></sec><sec><title>РЕЗУЛЬТАТЫ</title><p>РЕЗУЛЬТАТЫ. Выявлено статистически достоверное (на 0,3 дптр) увеличение РА в группах СТЭ и Ex-PRESS спустя полгода. Установлена достоверная корреляция (r=-0,497, p=0,002; r=-0,405, p=0,006) между уровнем РА и некорригированной остротой зрения (НКОЗ) для СТЭ и Ex-PRESS. В группе Ahmed изменения РА были незначимыми. СТЭ вызывала достоверное увеличение преломляющей силы  «крутого» меридиана (с 44,79±1,79 до 45,08±1,12 дптр, p=0,002) спустя полгода после операции. У пациентов с Ex-PRESS наблюдалось уменьшение преломляющей силы плоского» меридиана через 6 месяцев после вмешательства (с 44,28±1,01 до 44,0±1,09 дптр, p=0,002). Имплантация Ahmed приводила к уменьшению преломляющей силы «плоского» (с 43,59±1,04 до 43,44±1,19 дптр, p=0,036), а также изменению оси «крутого» меридиана (от условно прямого в 88,6±50,5° до косого в 71,4±48,9°, p=0,057).</p></sec><sec><title>ЗАКЛЮЧЕНИЕ</title><p>ЗАКЛЮЧЕНИЕ. Увеличение роговичного астигматизма после СТЭ и Ex-PRESS является важной причиной снижения НКОЗ. Для пациента это означает необходимость подбора новых корригирующих очков или коррекции астигматизма с помощью торических ИОЛ в ходе факоэмульсификации. Имплантация Ahmed практически не влияет на роговичный астигматизм и, как следствие, не снижает НКОЗ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>PURPOSE</title><p>PURPOSE: To assess keratometric changes after trabeculectomy (TE), Ex-PRESS shunt (EXP) and Ahmed glaucoma valve (AGV) implantation.</p></sec><sec><title>METHODS</title><p>METHODS: The study included 196 patients divided in 3 groups: TE group (n=116), EXP group (n=28) and AGV group (n=52). Each patient underwent keratometry (Topcon-8800) and corneal topography (Tomey RT-7000) proir to the surgery, 1 month and 6 months after intervention. Preoperative and postsurgical data were compared to assess keratometric values changes.</p></sec><sec><title>RESULTS</title><p>RESULTS: Corneal astigmatism (CA) magnitude increased by 0.3 D 6 months after TE and EXP. There was a significant correlation between CA magnitude and uncorrected visual acuity (UCVA) in TE and EXP groups (r=-0.497, p=0.002; r=-0.405, p=0.006, respectively). AGV implantation did not lead to significant changes in CA magnitude. Steep corneal meridian increased from 44.79±1.79 to 45.08±1.12 D  (p=0.002) 6 months after TE. EXP implantation decreased flat meridian from 44.28±1.01 to 44.0±1.09 D (p=0.002). There was a decrease of flat corneal meridian from 43.59±1.04 to 43.44±1.19 D (p=0.036), as well as a change of the steep meridian axis from 88.6±50.5 to 71.4±48.9 deg (p=0.057) in AGV group.</p></sec><sec><title>CONCLUSION</title><p>CONCLUSION: Decline of UCVA is associated with an increased CA magnitude after TE and EXP. Thus, patients should be informed that prescribing new spectacles or toric intraocular lens implantation due to upcoming phacoemulsification is a frequent perspective after these types of glaucoma procedures. Nevertheless, AGV implantation has no significant impact on CA magnitude and does not affect UCVA.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>кератометрия</kwd><kwd>хирургически индуцированный астигматизм</kwd><kwd>синустрабекулэктомия</kwd><kwd>шунт Ex-PRESS</kwd><kwd>клапан Ahmed</kwd><kwd>глаукома</kwd></kwd-group><kwd-group xml:lang="en"><kwd>keratometry</kwd><kwd>surgically induced astigmatism</kwd><kwd>trabeculectomy</kwd><kwd>Ex-PRESS shunt</kwd><kwd>Ahmed glaucoma valve</kwd><kwd>glaucoma</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Levene R.Z.
