AIMS: The purpose of this study is to evaluate an Altmetric analysis of the 50 most cited refractive surgery articles in Ophthalmology journals and to compare them with traditional metrics. METHODS: The term "refractive surgery" was searched, using a time filter between 2010-2020 in the Web of Science core collection database. The 50 most cited articles between 2010 and 2020 were recorded. Descriptive statistics were performed. The Spearman correlation test was used to evaluate the correlation between traditional metrics and Altmetrics. RESULTS: The Altmetric scores of the top 50 articles ranged from 0 to 25, and the median Altmetric score was 4. The citation numbers of the 50 articles ranged from 83 to 523, and the median citation number was 119.5. The most cited article topic was "Toric Intraocular Lens"; the topics with the highest Altmetric scores were "Toric Intraocular Lens" and "Trifocal Intraocular Lens". There was no significant correlation between Altmetric scores and number of citations. There was a weak correlation between Altmetric scores and the average citation per year. CONCLUSION: The Altmetric score is insufficient, compared with traditional metrics, to show the scientific value of articles on refractive surgery. Altmetrics can be used to supplement traditional metrics.

The leading topic of this particular paper is dedicated to available surgical options for refractive eye disorders treatment including surgery of cornea and intraocular surgery. Corneal Surgery includes laser refractive surgery - LASIK (Laser-Assisted In Situ Keratomileusis), FemtoLASIK (Femtosecond laser-assisted LASIK), PRK (Photorefractive keratectomy). This article describes relevant principles of particular procedures, indications and possible contraindications. The chapter dedicated to corneal implants provides information about ICRS (Intrastromal Corneal Rings Segment) and Inlays (corneal implants for presbyopia correction). Corneal interventions also include incision methods for astigmatism correction AK (Astigmatic Keratotomy) and LRI (Limbal relaxing Incisions). Intraocular refractive interventions preserving natural human lens also include phakic lenses. Relevant categorization, examples, indications and contraindications are listed in particular chapter of this paper. Intraocular refractive surgery which replaces the original human lens is also called RLE (Refractive Lens Exchange) or PRELEX (Presbyopic Lens Exchange). These interventions are usually accompanied with the multifocal intraocular lens implantation. This chapter provides the list of specific lens types, indications and contraindications related to this type of intervention. The last chapter describes Bioptics--the combination of corneal and intraocular surgery.
A corneal stromal lenticule (CSL) is a part of the corneal stroma that forms as a waste product during the refractive surgery ReLEx SMILE (Small Incision Lenticule Extraction) and is no longer used. With the increasing number of ReLEx SMILE procedures and the number of potentially available CSLs, two main aspects of their usage are currently being investigated. The first aspect includes the biological properties of CSLs and their proper preservation with respect to long-term storage. The second aspect is related to the potential clinical use of CSLs. As a high-quality biomaterial, CSLs have substantial potential to be used for alternative solutions in the treatment of specific eye diseases. In a number of studies it has been shown that RSL transplantation could be a safe and effective method that does not cause any serious complications, for example in terms of immune reaction. The aim of this article is to present an overview of the possibilities for using CSLs for transplantation purposes, and at the same time to discuss our methodology for processing and preserving CSLs with the protocol used at the Eye Tissue Bank of the Královské Vinohrady University Hospital.

The authors present a case of a thirty-eight-year-old patient with Alport syndrome. The patient had several ocular symptoms of the disease and has been treated for systemic problems in connection with Alport syndrome since he was fifteen years old. At that age the patient also underwent a kidney transplant in order to deal with renal insufficiency. To date, he still uses immunosuppressants and antihypertensives. Furthermore, the patient suffers from perceptive deafness. The patient visited our clinic in 2021 with a request to solve his high refractive error, in which the diopters were so high that it was not possible to place them in spectacles. The patient's best corrected visual acuity was 0.6 with -8.0sph/-4.0cyl/ax15 in the right eye and 0.7partim with -8.0sph/-4.0cyl/ax155 in the left eye. The autorefractometer values were -6.25sph/-6.75cyl/ax17 in the right eye and -6.75sph/-6.5cyl/ax155 in the left eye. During the eye examination we found a number of ocular manifestations that are typical of Alport syndrome. On the cornea there were opacities as a residue of corneal erosions, and at one of the following check-ups we also found a newly developed corneal erosion. Subsequently, we found an anterior lenticonus and incipient cataract. Upon performing OCT, a typical temporal macular atrophy was evident. Fundus examination in artificial mydriasis showed just a minimal manifestation of fleck retinopathy. Due to the clinical manifestation we decided to perform cataract surgery and implant a monofocal toric intraocular lens in both eyes. There were no complications during the operations, however the surgeon registered a non-standard structure of the lens capsule. The capsule was more fragile, and performing capsulorhexis was much more complicated. A week after the surgery, higher cylinder diopters were still present. A decrease of the higher diopters was noticeable one month after surgery. The time interval between the first operation and the second operation was one month. The patient was highly satisfied with result, and uncorrected visual acuity improved by over four lines. After surgery the patient needed low diopters for near as well as far distance. In the case of this patient, the ocular manifestations were detected and treated in adulthood. Nevertheless, early detection of ocular symptoms of Alport syndrome in young patients before renal failure could lead to timely start of the treatment and delay a possible renal transplant. In case of any suspicion of Alport syndrome it is advised to send the patient to a pediatrician, and at an older age to an internal medicine specialist, for further examination.

PURPOSE: To evaluate changes in corneal refractive parameters after implantation of a stromal lenticule of different thickness. We assume that the refractive outcome depends on the optical power of the used lenticule. METHODS: We conducted an ex-vivo non-human study on 33 normotonic porcine eyeballs divided into two groups, for 4D and 8D human lenticule implantation. Corneal stromal lenticules were obtained as a by-product from a laser procedure ReLEx SMILE. We evaluated corneal refractive parameters measured on Oculus Pentacam© device before and immediately after the intrastromal lenticule implantation. RESULTS: There was no statistically significant difference in corneal refractive parameters between the eyeball groups before lenticule implantation. In both groups, the intrastromal implantation in the depth of 300um led to a significant increase of central corneal pachymetry and corneal anterior steepening. In the 4D group the average central corneal pachymetry increased from 903 ± 124.59 to 1230 ± 148.99 (p = 0.0022) and in 8D group from 733.35 ± 69.60 to 1109 ± 161.64 (p = 0.0008). Induced changes in other studied parameters were not statistically significant, Kmax changed from 45.57 ± 2.78 to 72.07 ± 16.83 (p = 0.0094) and Km front from 40.72 ± 1.60 to 48.87 ± 5.83 (p = 0.0037) in 4D group and in the 8D group average Kmax increased from 42.22 ± 1.54 to 62.95 ± 12.67 (p = 0.0001) and K2 front 40.46 ± 1.64 to 51.51 ± 9.63 (p = 0.0037). There were no significant differences in refractive changes between the 4D and 8D groups after lenticule implantation. CONCLUSION: Intrastromal corneal lenticule implantation induces changes in corneal refractive parameters. In both groups, the implantation induced a significant increase of an anterior corneal steepening without any significant influence on posterior corneal flattening. Corneal lenticule implantation did not lead to any significant change of corneal astigmatism. However, in order to have more precise data for future clinical applications we need to continue with the experiments and verify the results on human corneas.

PURPOSE: To retrospectively evaluate postoperative outcomes and intraoperative and postoperative complications of clear lens extraction (CLE) with posterior chamber intraocular lens (IOL) implantation for high refractive errors. PARTICIPANTS: Sixty five (65) patients (129 eyes) who had undergone CLE with posterior chamber IOL implantation from 6/1999-6/2001. We chosen this method for all patients after exclusion of other methods of refractive surgery. The mean follow-up in all patients was 23,2 months (range 24 to 36 months). Eyes were divided into group A (myopia) with 13 patients (5 men, 8 women), average age 44.76 years (range 25 to 66 years) and group B (hyperopia) with 52 patients (24 men, 28 women), average age 49.47 years (range 27 to 64 years). RESULTS: Group A. The mean preoperative spherical equivalent refraction was -11.05 +/- 3.56 Dsf (range -15.5 Dsf do -3.5 Dsf), the mean postoperative spherical equivalent refraction was -1.17 +/- 1.04 Dsf (range -2.75 Dsf do 0 Dsf). The mean preoperative uncorrected visual acuity (UCVA) (decimal equivalent) was 0.02 +/- 0.009, the mean postoperative UCVA was 0.34 +/- 0.26. The mean preoperative best-corrected visual acuity BCVA was 0.57 +/- 0.32, the mean postoperative BCVA 0.65 +/- 0.24. Group B. The mean preoperative spherical equivalent refrection was +5.36 +/- 2.21 Dsf (range +2.00 Dsf to +13.0 Dsf). The mean postoperative spherical equivalent refraction was +0,0 7 +/- 0.89 Dsf (range -1,5 Dsf do + 4.5 Dsf). The mean preoperative uncorrected visual acuity (UCVA) was 0.13 +/- 0.12, the mean postoperative UCVA was 0.53 +/- 0.23. The mean preoperative best-corrected visual acuity BCVA was 0.76 +/- 0.28, the mean postoperative BCVA 0.69 +/- 0.27. No significant complications were observed. CONCLUSIONS: Refractive lensectomy with posterior chamber IOL implantation is safe, predictable, and effective. RL can achieve excellent visual acuity and refractive outcome with few complications.

UNLABELLED: Our study evaluated the visual and refractive results of LASEK and anterior chamber phakic intraocular lens (pIOL) implantation performed for high myopic anisometropia with amblyopia and contact lens intolerance in children compared with conventional treatment by contact lenses.Fourty-three patients (Group A) aged 3 to 7 years (mean, 5,6 years) with high myopic anisometropia and amblyopia had performed multizonal LASEK (27 eyes) or pIOL Verisyse implantation (16 eyes) on the more myopic eye in general anesthesia. Surgery was followed by patching of the dominant eye. Postoperative visual and refractive outcomes were analyzed and all children had minimally two years follow-up after procedure. Refractive surgical data were reported in standard format to describe safety, efficacy, predictability and stability of the procedure. This Group A of 43 children was compared with control Group B of 37 children (mean age 5,4 years), in whom myopic anisometropia and amblyopia were treated conventionally by contact lenses (CL) and patching of the dominant eye. Visual acuity (VA) and binocular vision (BV) outcome were analyzed and compared in both groups.The mean preoperative spherical equivalent (SE) cycloplegic refraction in Group A was - 9,45 ± 2,47 diopters (D) (range -6.0 to -18.25 D) and the mean postoperative SE -1,48 ± 1,13 D (range + 0,75 to - 2,25 D). The mean preop. decimal uncorrected visual acuity (UCVA) 0,023 ± 0,017 increased to 0,46 ± 0,18. The mean preop.decimal best-corrected visual acuity (BCVA) in Group A was 0,28 ± 0.22 and changed to 0,78± 0,19 by 2 years after surgery. The mean BCVA in Group B was 0,23 ± 0,19, at start of CL correction and amblyopia therapy, and improved to 0,42 ± 0,15 after two years. The mean BCVA at final examination was significantly better in Group A (P < 0,05). Binocular vision improvement expressed by the proportions of subjects gained fusion and stereopsis, was overall better in Group A (81 %) than in Group B (33 %), (P < 0,05). There were no complications after surgery.Refractive surgery in children, multizonal LASEK and pIOL Verisyse implantation, are effective and safe methods for correction of high myopic anisometropia, and has an important role in the treatment of amblyopia in children when contact lens intolerance. Visual acuity and binocular vision outcomes were better in children who received permanent surgical correction of anisometropia, than in children conventionally treated by contact lenses. KEY WORDS: myopic anisometropia, amblyopia, children, laser subepithelial keratomileusis (LASEK), anterior chamber phakic intraocular lenses (AC pIOL), binocular vision.
