“…В работе I-T. Sun и соавт. [2] получены данные, отличающиеся от наших. Миопический сдвиг при односторонней артифакии был значительно больше, чем при двусторонней артифакии (-7,68 ± 5,04 и -3,88 ± 2,47 дптр соответственно), что связано не с чрезмерным ростом глаза, а с недостаточной величиной гипокоррекции ИОЛ, имплантируемой детям раннего возраста.…”

“…Развитие и прогрессирование миопии у детей после экстракции врожденной катаракты (ВК) с имплантацией ИОЛ в грудном возрасте являются одной из основных проблем реабилитации таких пациентов [1][2][3][4]. В ряде исследований показано влияние величины астигматизма на скорость процесса эмметропизации и последующего развития миопии в части случаев у детей без сопутствующей патологии [5][6][7].…”

“…Вызывая неравномерный периферический дефокус на сетчатке, он способствует чрезмерному росту глаза и приводит к развитию осевой миопии. В то же время, по данным многих авторов, имеются различия в миопическом сдвиге при односторонней и двусторонней патологии [2,[9][10][11]. S. McClatchey и соавт.…”

“…Такие же данные получены в работе I.-T. Sun и соавт. : через 4-5 лет после проведения экстракции ВК с имплантацией ИОЛ в возрасте старше 5 мес миопический сдвиг при односторонней артифакии был значительно больше, чем при двусторонней артифакии [2]. Различия в изменении по-слеоперационной рефракции у детей в зависимости от характера патологии свидетельствуют о разных факторах развития и прогрессирования миопии у таких детей и необходимости анализа влияния астигматизма на развитие близорукости у детей с односторонней и двусторонней артифакией.…”

After the extraction of congenital cataract in infancy, postoperative refraction changes differently in patients with bilateral and unilateral pseudophakia. Purpose: to compare myopia development in children with bilateral and unilateral pseudophakia. Material and methods. We examined 33 children (63 eyes) with bilateral and 21 children with unilateral pseudophakia for long-term results of congenital cataract extraction performed in their infancy, The evaluated parameters included the incidence and degree of myopia, refraction, general postsurgical astigmatism, and axial length of the eye. Refraction was measured by Nidek ARK-530A (Japan). The axial length was measured by ultrasound B-scan (Voluson E8, GE) or by optical biometry (AL-Scan, Nidek). Results. In bilateral pseudophakia, high myopia was detected if astigmatism was more than 3.25 D or oblique. In the latter case, the eyeball showed a greater growth as compared to with-the-rule astigmatism (4.67 mm and 3.26 mm, respectively; p < 0.05). With incomplete correction of astigmatism in the case of bilateral pseudophakia, myopia progressed to a high degree in nearly half of the cases (48.1 %), and a greater growth of the eye was detected compared with complete correction (4.45 mm and 3.42 mm respectively; p > 0.05). The type and degree of astigmatism did not affect the development and progression of myopia in unilateral pseudophakia. Conclusion. The effect of undercorrected astigmatic defocus on the development and progression of myopia in bilateral pseudophakia is apparently associated with a equivalent visual load on both eyes, while this load is significantly reduced in unilateral pseudophakia so that it fails to affect the development of myopia in such cases.

One of the serious challenges facing surgeons after congenital cataract extraction with IOL implantation in infancy is unplanned refractive results revealed in the long-term period, including the cases of myopia higher than 3.0 D in approximately 50 %. Purpose. The study aimed to evaluate the clinical and functional condition of the eyes in children with moderate to high myopia. Material and methods. Our study included a total of 33 patients (61 eyes) with pseudophakia, of which 16 (26 eyes) developed moderate (12 eyes) or high (14 eyes) myopia at the age of 5 to 15 years. Parameters of the anterior and posterior eye segments were evaluated using Galilei Dual Scheimpflug Analyzer and Optical Coherence Tomography RS-3000 Advance 2, and the axial length using Optical Biometer Al-Scan. Results. The central corneal thickness (CCT) was found considerably above the norm (up to 580 ± 35 pm) in most cases of pseudophakic myopia (72.2 %). Anterior chamber depth in children (4.07 ± 0.39 mm) was equal to that in adults with pseudophakia. Astigmatism and axial length in children with highmyopia significantly exceeded those in children with moderate myopia (3.5 and 1.88 D; 23.57 ± 1.31 and 25.04 ± 1.90 mm, respectively), while choroidal thickness and best corrected visual acuity (BCVA) were much lower (268 and 181 pm; 0.1 and 0.3, respectively). There were no variations in spherical equivalent between different axial length in high and moderate myopia. Conclusion. Taken together these results suggest that with the increase of astigmatism axial length elongated and high myopia developed in children with pseudophakia. Choroidal thickness declined due this process and may be a cause of poor functional outcome. Sufficient CCT opens possibilities for refractive surgery in those patients to improve visual outcomes.
