Objective: Comparison of complications development rate in various methods for implanting intraocular lenses (IOLs) in the surgical treatment of congenital cataract.Methods: The results of surgical treatment of 16 children under 5 years old with bilat‑ eral congenital cataract were assessed. In each case, IOL was implanted according to the technique “optic capture” into one eye (the 1st group of study); the lens was implanted after capsulorrhexis and extraction of anterior segments of vitreous body into the second eye (the 2nd group of study).Results: Fibrinoplastic complications in the postoperative period were more often recorded in the 2nd group than in the 1st one (5 and 1 eyes, respectively). Epithelial proliferation in the 2nd group developed in 10, in the 1st group – in 5 eyes.Conclusions: In the surgical treatment of congenital cataract, implantation of IOLs according to the technique “optic capture” is an effective way of epithelial proliferation and opacity prevention reducing visual acuity in postoperative period. This method is safe regarding inflammatory fibrinoplastic reactions and allows maintaining normal anatomical position of the vitreoretinal structures of the growing eye.

Aim: to analyze the data obtained from using of intraocular lenses — the hydrophobic IOL Citrin and a hydrophilic IOL Aquamarine, produced by Russian company — NanOptic. Materials and methods. A total of 56 IOLs, produced by NanOptic (38 hydrophobic IOLs Citrine and 18 hydrophilic IOLs Aquamarine) were implanted. The observation period was from 3 to 12 months. The indication for phacoemulsification was age cataract. The age of the patients was 54–85. Patients before the operation were conducted basic studies. The mean uncorrected visual acuity before the operation was (UCVA) 0.121 ± 0.120 (0.001–0.3), and the mean corrected visual acuity was (BCVA) 0.187 ± 0.140 (0.001–0.6). All patients underwent standard phacoemulsification. Results. The early postoperative period was without any complications. In the postoperative period the mean UCVA in patients with “Citrine” and “Aquamarine” was 0.90 ± 0.10 (0.7–1.0) and 0.96 ± 0.07 (0.8–1.0) accordingly, and the mean BCVA was 0.94 ± 0.07 (0.8–1.0) and 0.99 ± 0.02 (0.9–1.0) accordingly. In all cases, the refraction obtained was consistent with the prediction. The error in IOL calculation was minimal and permissible. There weren’t any case of secondary cataract in patients with hydrophobic IOLs, and 3 cases of lens posterior capsule fibrosis of 1 degree in patients with hydrophilic IOLs in 3–12 months observation. The position of IOL in capsule bag was stable. Conclusions. The results of implantation of new Russian-made IOLs on the given parameters appeared to be satisfactory, that allows to recommend them for implantation in cataract surgery.

Aim. To assess the efficacy of laser photocoagulation treatment for patients with chronic central serous chorioretinopathy. Methods. The study included 17 eyes of 15 patients with relapse of central serous chorioretinopathy of different etiology, including 9 men. Patient’s age ranged from 34 to 55 years. Mean disease duration ranged from 3 months to 8 years. All study subjects underwent a standard ophthalmic examination including best-corrected visual acuity testing, intraocular pressure measurement, bioophthalmoscopy, color vision testing, visual field testing, optical coherence tomography, fluorescent angiography of the retina before and after the treatment. Fluorescein sodium salt (100 mg/ml, ampules of 5 ml, «Novartis Pharma» was used as a contrast. Before the treatment, neuroepithelial layer detachment height was 385.09±14.1 µm, the best-corrected visual acuity ranged from 0.41 to 0.82. The study group did not include the patients with secondary choroidal neovascularization. Diode laser with wave length of 532 nm («Carl Zeiss») was used for laser photocoagulation. The laser photocoagulation procedure was done using the following parameters: exposure time 0.05-0.1 sec, the spot diameter 100-200 µm, and the impulse energy of 100-200 mJ. Results. Significant improvement of visual acuity, disappearance of relative central scotoma proven by instrumental methods was seen in all patients. Best-corrected visual acuity was 0.91, decrease of neuroepithelial layer detachment height with adherence of all layers of the retina was reduced to 171.12±11.5 µm on the 3-5 day after laser photocoagulation. Patients were followed up from 1 to 6 months, with treatment results staying stable. Conclusion. Laser photocoagulation of a retina in treatment of chronic central serous chorioretinopathy allows to achieve encouraging morphologic and functional results.

During the last decade multifocal intraocular lenses (IOL) became widely used in cataract surgery and proved to be effective in recovery of visual functions. Lots of clinical studies with different multifocal IOL models showed high effectiveness of multifocal correction to achieve good visual quality for far, intermediate, and near distances. Uncorrected visual acuity at a distance is equal to multifocal and monofocal correction, while uncorrected near vision is significantly better with multifocal IOLs. Additional segment position in asymmetric multifocal IOL models did not significantly influence on visual acuity. Multiple multifocal IOL designs (bifocal, trifocal) and ADD power level provide different functional results for near and intermediate distances which allows to select the specific IOL model depending on the patient`s needs. The review covers the following aspects of multifocal intraocular correction: update for classification of multifocal IOLs, visual acuity (functional results) at different distances after multifocal IOL implantation, comparison of clinical results with different multifocal IOL designs and add power levels, influence of add segment position in asymmetric multifocal IOLs on visual quality, comparison between multifocal and monofocal correction.

Phakic Intraocular Lenses

The purpose of this study was to examine visual function and eye structure before and after implantation of an intraocular lens in the phakic posterior chamber of the eye, for the correction of extreme myopia. Thirty subjects with 12∼ –27 diopters of extreme myopia were implanted with posterior chamber phakic intraocular lenses, and followed-up for 3–27 months. The follow-up examinations included uncorrected visual acuity (UCVA), best corrected visual acuity (BSCVA), intra ocular pressure (IOP), refractive power, lens transparency, intra ocular lens (IOL) position, endothelial cell density (ECD), anterior chamber depth (ACD), axial length, near point of accommodation, and macular retinal thickness. All indices improved after the surgery. These results demonstrate that the implantable collamer lens (ICL) for extreme myopia can effectively improve vision, and does not have negative effects on eye structure and accommodation.

AbstractThis meta-analysis aimed to evaluate the clinical outcomes following implantation of trifocal intraocular lenses (IOLs) or a hybrid multifocal-extended depth of focus (EDOF) IOL in cataract or refractive lens exchange surgeries. We examined 13 comparative studies with bilateral implantation of trifocal (898 eyes) or hybrid multifocal-EDOF (624 eyes) IOLs published through 1 March 2020. Better uncorrected and corrected near visual acuity (VA) were observed in the trifocal group (MD: − 0.143, 95% CI: − 0.192 to − 0.010, P < 0.001 and MD: − 0.149, 95% CI: − 0.217 to − 0.082, P < 0.001, respectively), while the hybrid multifocal-EDOF group presented better uncorrected intermediate VA (MD: 0.055, 95% CI: 0.016 to 0.093, P = 0.005). Trifocal IOLs were more likely to achieve spectacle independence at near distance (RR: 1.103, 95% CI: 1.036 to 1.152, P = 0.002). The halo photic effect was generated more frequently by the trifocal IOLs (RR: 1.318, 95% CI: 1.025 to 1.696, P = 0.031). Contrast sensitivity and subjective visual quality yielded comparable results between groups. Trifocal IOLs demonstrated better performance at near distance but apparently led to more photic disturbances. Our findings provided the most up-to-date and comprehensive evidence by comparing the benefits of advanced IOLs in clinical practice.

AimsCraniosynostosis is a congenital condition characterised by premature fusion of one or more cranial sutures. The aim of this study was to analyse ophthalmic function before and after cranial surgery, in children with various types of non-syndromic craniosynostosis.MethodsChildren referred to Uppsala University Hospital for surgery of non-syndromic craniosynostosis were examined preoperatively. Visual acuity was measured with Preferential Looking tests or observation of fixation and following. Strabismus and eye motility were noted. Refraction was measured in cycloplegia and funduscopy was performed. Follow-up examinations were performed 6–12 months postoperatively at the children’s local hospitals.ResultsOne hundred twenty-two children with mean age 6.2 months were examined preoperatively. Refractive values were similar between the different subtypes of craniosynostosis, except for astigmatism anisometropia which was more common in unicoronal craniosynostosis. Strabismus was found in seven children, of which four had unicoronal craniosynostosis.Postoperatively, 113 children were examined, at mean age 15.9 months. The refractive values decreased, except for astigmatism and anisometropia in unicoronal craniosynostosis. Strabismus remained in unicoronal craniosynostosis. Two new cases with strabismus developed in unicoronal craniosynostosis and one in metopic, all operated with fronto-orbital techniques. No child had disc oedema or pale discs preoperatively or postoperatively.ConclusionOphthalmic dysfunctions were not frequent in children with sagittal craniosynostosis and preoperative ophthalmological evaluation may not be imperative. Children with unicoronal craniosynostosis had the highest prevalence of strabismus and anisometropia. Fronto-orbital techniques used to address skull deformity may be related to a higher prevalence of strabismus postoperatively.
