Purpose: To compare the accuracy of intraocular lens power calculation formulas and to examine the correlation of this exactness with the axial length for eyes shorter than 22.00 mm Methods: The data of hyperopic patients who underwent uneventful phacoemulsification between October 2015 and June 2019 were reviewed. The intraocular lens power for each patient was calculated using 6 formulas (Holladay1, SRK/T, Hoffer Q, Holladay 2, Haigis and Barrett Universal II) before cataract surgery. Postoperative refraction was measured, and refractive prediction error was calculated 3 months after phacoemulsification. The correlation between axial length and absolute error was evaluated. Results: Fifty-six patients (62 eyes) whose ocular axial length ranged between 20.58 mm and 21.97 mm were included in the study. The Hoffer Q formula achieved the lowest mean absolute error of 0.09 (±0.08 D). A significant correlation for the Hoffer Q (ρ = -0.329, p = 0.009) and the SRK/T (ρ = 0.321, p = 0.011) formula was observed. Conclusions: 1. The Hoffer Q formula obtained the lowest absolute error and was recommended for intraocular lens power calculation for eyeballs with axial length shorter than 22.0 mm. 2. The correlation between axial length and absolute error is a factor which should be considered when calculating intraocular lens power.

PURPOSE: To evaluate the efficacy of epithelium-on photorefractive intrastromal crosslinking (PiXL), a noninvasive procedure to reduce refractive error in patients with low hyperopia. SETTING: Gemini Eye Clinic, Zlin, Czech Republic. DESIGN: Prospective single-center study. METHODS: Twenty-two low hyperopic eyes were enrolled and underwent PiXL treatment according to a standardized treatment protocol. Visual acuity, subjective distance refraction, keratometry, topography, pachymetry, subjective discomfort, and endothelial cell density (ECD) were recorded during 12-month follow-up. RESULTS: In 22 eyes, the median manifest refraction decreased significantly (P < .0001) from +0.75 diopters (D) (interquartile range [IQR], +0.63 to +1.06 D), median and IQR) diopters (D) preoperatively to +0.25 D (IQR, 0.0 to +0.50 D) at 12-month follow-up and remained stable. Seventy-seven percent of eyes achieved refraction within ± 0.50 D of emmetropia by 1 month postoperatively and was stable through 12-month follow-up. ECD was stable and did not show significant changes. There was low incidence of postoperative pain and dry eye. CONCLUSIONS: PiXL is a promising alternative to conventional laser refractive surgeries for low hyperopia. Further studies are warranted to optimize treatment parameters for a wider range of refractive errors and to evaluate the potential to improve precision.

The authors present a case report of a three-year-old female patient with bilateral multiple anterior vitreous cysts. During examination for intermittent esotropia of the right eye was diagnosed not only hypermetropia, astigmatism and anisometropia, but also pigmented changes in peripheral retrolental space of both eyes. Clinical examination under general anaesthesia revealed bilateral multiple pigmented immobile vitreous cysts. There were five almost spherical, translucent, but slightly pigmented cysts on its cover on the right eye and four similar on the left, but visible only with dilated pupils. A dilating of pupils was slow and required more mydriatics than in similar aged children. Follow up period is ten years now. Occlusion therapy of amblyopia was performed to nine years of age. Treatment of refractive error and esotropia with correction for hypermetropia, astigmatism and anisometropia continues. Best corrected visual acuity in thirteen-year-old girl is 1,0 in both eyes without any visual disturbances described by patient. Corrected visual acuity in each eye is 1,0, right eye with +3,5 D sph., -3,5D cyl., axis 175°, left eye with +7,5 D sph., -3,0 D cyl., axis 35°. Patient is otherwise healthy and without any mental deficit. Position of all cysts remains unchanged and stabile during the follow up period (with recommendation to avoid hits to the head for all time, mainly in sports). Formation and slow progression of partial cortical cataract in the area of contact of the lens and one cyst in inferonasal quadrant of the lens on the right eye is monitored. A lamellar retinal extrafoveal defect of posterior pole of the right eye was found by OCT imaging.

Aim: To evaluate late postoperative complications, especially cataract occurrence, its morphological type and factors affecting its development in patients implanted with ICL (Implantable Collamer Lens). Methods: We analysed results of ICL implantation in 34 patients (type ICM V4 for myopia, ICH V3 for hyperopia, TICM V4 for astigmatism) in our department between 1998 and 2013. It comprised 62 eyes (40 myopic and 22 hyperopic). Seven eyes with toric ICL implanted were included into these groups according to spherical equivalent (SE). The average follow -up period was 10.5 ± 3.5 years. We examined: uncorrected and best-corrected visual acuity (UCVA and BCVA), SE, ICL vaulting (using anterior segment OCT) and occurrence of late postoperative complications, especially cataract formation in 2 groups of patients – myopes and hyperopes. Results: Among the most common late postoperative complications were pigment dispersion in 27 eyes, 43,5% (12 myopic eyes and 15 hyperopic eyes) and cataract formation. Lens opacities occurrence, including opacities without loss of BCVA, was observed in 18 eyes (29%). Opacities affecting visual acuity were observed in 10 eyes (16,1%). Cataract significantly affecting visual acuity occurred in 7 eyes, i.e. 11,3%, (in 5 myopic eyes and 2 hyperopic eyes). In these eyes, ICL removal and cataract surgery with implantation of posterior chamber intraocular lens (PC IOL) was performed. The most common morphological type of cataract were anterior subcapsular opacities (83.3%), the average time of onset was 3.4 ± 1.9 years after ICL implantation. We did not prove statistically significant association neither between cataract occurrence and age at the time of surgery, nor between cataract occurrence and higher preoperative spherical equivalent. We did not prove significant association between cataract occurrence and low vault, however in 7 eyes after cataract surgery and ICL removal we do not know the vault values. In one eye uveitis with cystoid macular oedema was observed, in two highly myopic eyes repeated ICL dislocation and cataract occurred. In both of these cases ICL was removed. Conclusions: According to our experience, implantation of ICL in moderate and high ametropia was relatively safe when assessing long-term outcomes. Among the most common complications were pigment dispersion and anterior subcapsular cataract formation. Cataract can be managed effectively surgically with good refractive outcomes without loss of BCVA. However loss of accommodation after cataract surgery and risk of vitreoretinal complications must be considered.
