“…Несомненно, коррекция рефракционных ошибок с помощью supplementary ИОЛ Sulcoflex и Add-on, серийно выпускаемых много лет, является рутинной процедурой, результаты подобной коррекции представлены во множестве публикаций [3][4][5][6][7][8][9][10][11], в том числе и в виде кандидатской диссертации 1 . Описан даже случай имплантации ИОЛ Sulcoflex в "upside-down" позиции, что, кстати, практически не повлияло на рефракционный результат [12].…”

In a number of complex refractive cases, the achievement of an accurate refractive result cannot be guaranteed. Simultaneous implantation of a toric or multifocal IOL for the correction of complex ametropias may be accompanied by a significant deviation from the target refraction. The tactics of two-stage implantation with the usage of an additional Sulcoflex IOL for the final correction of astigmatism and possible residual spherical ametropia allows achieving emmetropia. In our study, this method was used in 15 patients with difficult refractive cases. Toric, multifocal, and multifocal toric Sulcoflex IOL were used. Implantation of all Sulcoflex modifications was performed through a 2.4 mm temporal incision using wound assisted technology. In cases of high degree hypermetropia, preventive iridectomy was performed using a 23G vitrectome. The target refraction was achieved in the entire observation group. In the postoperative period, no significant level of ophthalmic hypertension was registered. No cases of introlens opacification, iridocyclitis, or rotational instability were registered either.The method of two-stage IOL implantation allows achieving the target refraction in difficult refractive situations with almost guaranteed accuracy. The calculation method provides good predictability of the refractive result. This technology significantly expands the indications for intraocular correction using toric and multifocal IOL, as well as the limits of correction of high degree astigmatism. Our Sulcoflex IOL implantation experience has shown their high efficiency and safety.

“…Выполнение лазерных рефракционных вмешательств у данной группы пациентов может быть альтернативой имплантации добавочной торической ИОЛ. Ранее нами были опубликованы данные наблюдения за пациентами с остаточным астигматизмом и имплантацией торических сулькусных ИОЛ Rayner Sulcoflex Toric [21] и Addon Torica-sPB [23]. В описанных сериях клинических случаев (7 и 3 пациента соответственно) достигнут оптимальный рефракционный эффект и отмечена высокая субъективная удовлетворенность пациентов.…”

“…В ряде работ показано, что лазерные рефракционные вмешательства -LASIK и ФРК -более точны и предсказуемы при коррекции небольших сферических и цилиндрических аметропий, в то время как добавочные ИОЛ и замена ИОЛ -при коррекции больших сферических аметропий [6][7][8][9]. В настоящее время накоплен значительный опыт отдельных исследований безопасности и предсказуемости применения лазерных рефракционных вмешательств для коррекции остаточных аметропий после хирургии катаракты [3,[8][9][10][11][12][13][14][15], рефракционной замены ИОЛ [16][17][18][19] и имплантации факичных [20] и добавочных [21] ИОЛ.…”

Purpose. Evaluation of the visual and refractive results of additional correction using LASIK and PRK methods in patients with residual refractive error after previous cataract surgery. Patients and methods. The prospective open study included 57 patients (79 eyes) who previously underwent cataract phacoemulsification (n = 37) or refractive lensectomy (n = 42) with various IOL models implantation (2012–2017). The average age of patients was 50.8 ± 13.9 (19–79) years. Operations LASIK (91.1 %) and PRK (8.9 %) were carried out according to standard methods. In 6 cases, femtosecond laser supported by laser correction. The target refraction ranged from –0.25 to 0.25 D in most (97.5 %) cases. The follow-up period ranged from 6 to 9 months. Results. The patients were divided into groups according to the type of residual refractive error (Group 1 — myopia, group II — emmetropia and group III — hyperopia). Statistically significant differences were determined for the species of previously implanted IOLs — in group II, the frequency of monofocal IOLs was significantly higher (p < 0.05). In group II, the values of the cylindrical component of refraction were significantly higher compared with groups I and III (p < 0.05). In group I, a significant (p < 0.05) decrease in the spherical component of refraction from –1.36 ± 0.92 to –0.2 ± 0.8 D was observed. In patients of group II, there was a slight increase in the spherical component of refraction from 0 ± 0.20 to 0.25 ± 0.29 D (p > 0.05). In group III, a significant (p < 0.05) decrease was observed in the spherical component of refraction from 1.27 ± 0.69 to 0.43 ± 0.49 D. When analyzing the cylindrical component of refraction in group I, its decline was noted from –0.69 ± 0.5 to –0.38 ± 0.46 D (p > 0.05). In group II, the largest decrease in the cylindrical component was observed from –1.6 ± 1.0 to 0.03 ± 1.10 Dptr (p < 0.01). In all the studied groups, a statistically significant (p < 0.05) increase in UCFVA was revealed in the postoperative period. Indicators K1 and K2 did not significantly change. Conclusion. The high efficiency of the correction using the LASIK, PRK and femtoLASIK methods on pseudophakic eyes with the achievement of the target refraction in most of the studied cases was shown. This method can be used as an alternative to spectacle and contact correction in patients with residual refractive error after cataract phacoemulsification and refractive lensectomy with IOL implantation.
