Purpose: to compare the clinical results of implantations of bi-and trifocal intraocular lenses (IOL) in femtosecond laser-assisted cataract surgery. Patients and methods. The article presents the results of the Acrysof IQ Panoptix trifocal lens implantations in 84 patients (112 eyes) — the main group and Acrysof IQ Restor bifocal IOL implantations in 52 patients (98 eyes) — the control group. All patients underwent femtosecond laser-assisted cataract surgery (FLACS). The following data were evaluated: uncorrected distance visual acuity (UCDVA) , uncorrected near visual acuity (30–45 cm) and at an average distance (50–70 cm) at discharge, after 14 days, 1 and 3 months after the surgery under photopic and mesopic lighting conditions. Postoperative refractometry data; the defocusing curve was performed in patients with a high UCDVA (0.9–1.0) monocularly under photopic conditions using standard optotypes 14 days after surgery; aberrometry indicators. Results. It was shown that both lenses provided high uncorrected distance and near visual acuity in photopic lighting conditions. At the same time, the Acrysof IQ Panoptix lens provided significantly better visual acuity at an intermediate distance and was more resistant to defocusing conditions. Refraction data: after 1 month, emmetropia was observed in 87 % of patients in the main group and in 85 % of control group, after 6 months — 92 and 89 % respectively. There were no significant differences in high order aberrations and total aberrations between patients of the compared groups. Conclusion. The use of the PanOptix trifocal lens made it possible to obtain maximum visual acuity at different distances, regardless of the level of illumination.

Improving Accuracy

Refractive surgery has become the most rapidly developing field in ophthalmology over the last two decades. Several modern refractive procedures have become available over the last 10 years including phakic intraocular lenses (pIOLs), epithelial laser-assistedin situkeratomileusis (epi-LASIK), wavefront-guided (WG) laser treatments and a few others. Laser and non-laser refractive surgical procedures are currently used to address refractive errors. No single procedure works best for everyone; each one has its own set of advantages and disadvantages. Careful patient selection is the key for optimum visual outcomes. Treatment algorithms have been refined over the years, improving accuracy. Laser technology and delivery platforms are under continuous improvement, leading to increasingly precise results. Further modifications and refinements are ongoing, offering expanding surgical options in this rapidly evolving field.

The article presents review of actual publications' data concerning surgical correction of presbyopia. The data is presented related to social significance of presbyopia alongside with other disorders of refraction. The techniques applying monovision include thermokeratoplasty and such its modification as laser and radio-frequency thermokeratoplasty. All of them have number of deficiencies. The exdmer-laser ablation of cornea in the form of Laser-Assisted in Situ Keratomileusis (LASIK) or Photorefractive keratectomy (PRK) are considered as kerato-refractional techniques of correction of presbyopia. The femtosecond laser intrastromal correction of presbyopia (INTRACOR) is also labeled as kerato-refractional technique of correction of presbyopia and it is based on making intrastromal concentric rings in the central optical zone of cornea. The deficiency of INTRACOR is a relatively high cost of procedure due to application of femtosecond laser. The implantation of inlays (artificial devices) into cornea permits correcting presbyopia with less financial expenses. However, there are number of contraindications for implementing. The Tornton and Schachar operations are referred to the group of sclerotic operations of correcting presbyopia. However, nowadays these interventions are practically out of application. The implantation of intraocular lenses, including accommodating, multi-focal and monofocal by the principle of monovision ones, can be considered as the most adequate mode of correction of presbyopia. The advantages and disadvantages of implantation of various types of intraocular lenses are considered in detail.

The Mean

Purpose. To report the outcomes of combined surgery using femtosecond laser-assisted cataract surgery (FLACS) and sutureless 27-gauge pars plana vitrectomy with intravitreal tamponade. Methods. This retrospective clinical study involved 23 eyes of 23 patients on whom combined vitreoretinal surgery was performed. Patients were initially given the femtosecond laser treatment that was performed after selection of capsulotomy and lens fragmentation patterns. The capsulotomy diameter was chosen as 4.9 mm in all patients. After the femtosecond laser, the sutureless phacovitrectomy procedure was performed. At the end of surgery, perfluoropropane or sterile air tamponade was applied. Results. The mean age of patients was 66.43 ± 7.61 (range, 54–83) years. Fifteen patients were females (65.2%). The mean follow-up was 16.09 ± 4.71 (range, 9–25) months. The most common surgical indication was epiretinal membrane (65.3%). The mean preoperative best-corrected visual acuity (BCVA) was 0.71 ± 0.44 (range, 1.7–0.3) logMAR, and the mean postoperative BCVA at 6 months was 0.16 ± 0.14 (range, 0.4–0) logMAR p<0.001. The mean target sphere refractive error was −0.24 ± 0.16 (range, −0.50–0.11) D, and the mean postoperative spherical equivalent refractive error was −0.14 ± 0.39 (range, −1.00–0.50) D at 6 months p=0.196. All intraocular lenses (IOLs) remained well centered in the capsular bag during surgery and follow-up. There was no iris capture, posterior synechiae, capsular opacification, or pseudophakic cystoid macular edema. The only complication related to femtosecond laser was two cases of subconjunctival haemorrhage related with suction. Conclusions. FLACS is a safe and effective technique providing the advantage of repeatable, precise capsulorhexis shape and size to achieve a well-centered and stable IOL postoperatively. These advantages can certainly improve the results of vitrectomy, especially in gas-filled eyes. FLACS and 27-gauge sutureless combined surgery may be a future trend in appropriate cases.
