Article Synopsis
- - The study investigates how minimizing the standard deviation (SD) of prediction errors (PE) before adjusting the mean PE affects the accuracy of intraocular lens (IOL) power calculations in cataract surgery.
- - Researchers analyzed data from 4885 eyes using four IOL formulas (SRK/T, Holladay 1, Haigis, Hoffer Q) and found that optimizing constants improved accuracy and reduced SD, particularly for Haigis and Hoffer Q.
- - The findings suggest that focusing on SD reduction enhances IOL calculation precision, leading to better postoperative outcomes, but results may vary depending on the specific calculation formula used.
Purpose: To evaluate the safety and effectiveness of bilateral refractive lens exchange (RLE) with trifocal intraocular lens (IOL) as the surgical treatment of presbyopia.
Settings: Memira AS. Norway, Sweden and Denmark.
Purpose: To describe an open-source, reproducible, step-by-step method to design sum-of-segments thick intraocular lens (IOL) calculation formulas, and to evaluate a formula built using this methodology.
Design: Retrospective, multicenter case series METHODS: A set of 4242 eyes implanted with Finevision IOLs (PhysIOL, Liège, Belgium) was used to devise the formula design process and build the formula. A different set of 677 eyes from the same center was kept separate to serve as a test set.
Purpose: To evaluate the refractive and biometry results of presbyopic refractive lens exchange (RLE) with trifocal intraocular lens (IOL) implantation in eyes with previous myopic or hyperopic corneal laser vision correction (LVC).
Settings: Memira AS, Norway, Sweden, and Denmark.
Design: Retrospective case series.
Purpose: To evaluate refractive results and the theoretical elastic response of photorefractive keratectomy in eyes with asymmetrical corneal surface and to compare such outcomes with a control-matched group of normal topographies.
Design: Retrospective interventional case series with matched comparison group.
Methods: Thirty eyes with superior-inferior dioptric difference (SI index) > 1.
Purpose: To evaluate the changes in corneal higher-order aberrations (HOAs) and their impact on corneal higher-order Strehl ratio after aberration-free ablation profile.
Setting: Verter Institute, H. Olhos, São Paulo, Brazil.
Purpose: To report the long-term refractive and optical quality outcomes of patients with intrastromal corneal ring segments (ICRS) to treat keratoconus and to analyze the results according to the patients' age.
Setting: Vissum Instituto Oftalmologico de Alicante, Alicante, Spain.
Design: Case series.
Purpose: To analyze the outcomes of intracorneal ring segment (ICRS) implantation for the treatment of keratoconus based on preoperative visual impairment.
Design: Multicenter, retrospective, nonrandomized study.
Methods: A total of 611 eyes of 361 keratoconic patients were evaluated.
Purpose: To evaluate the visual outcomes after laser in situ keratomileusis (LASIK) surgery to correct primary compound myopic astigmatism with high cylinder performed using a fast-repetition-rate excimer laser platform with optimized aspheric profiles and cyclotorsion control.
Setting: Vissum Corporation and Division of Ophthalmology, Universidad Miguel Hernández, Alicante, Spain.
Design: Retrospective consecutive observational nonrandomized noncomparative case series.
Purpose: To evaluate clinical results of intrastromal corneal ring segments (ICRS) in a large series of post-laser in situ keratomileusis (LASIK) ectasia and determine which clinical parameters were related to the success of this technique.
Settings: Vissum Corporation and Clínica Baviera Group, Alicante, Spain.
Design: Case series.
Purpose: To evaluate and characterize the main clinical features of post-laser in situ keratomileusis (LASIK) ectasia, propose a grading system based on visual limitation, and identify predictive factors related to the degree of visual loss.
Setting: Vissum Corp., Alicante, Spain.
