Kết quả lâm sàng với thiết kế mới trong thủy tinh thể đa tiêu điểm: một nghiên cứu thí điểm Dịch bởi AI
Eye and Vision - Tập 7 - Trang 1-9 - 2020
Để đánh giá kết quả lâm sàng và thị lực, chất lượng thị lực gần và ảnh hưởng của các hiện tượng ánh sáng đối với bệnh nhân được cấy ghép hai bên một loại thủy tinh thể đa tiêu điểm Presbyopic mới (IOL) có tên Precizon. Trong nghiên cứu kết hợp theo dõi liên tục này, 20 mắt của 10 bệnh nhân được đưa vào (tuổi trung bình 63.80 ± 12.55 năm). Tình trạng thị lực không chỉnh và chỉnh (xa, trung gian và ......

Scleral surgery for the treatment of presbyopia: where are we today?
Eye and Vision - Tập 5 - Trang 1-11 - 2018
Presbyopia corrections traditionally have been approached with attempts to exchange power, either at the cornea or the lens planes, inducing multifocality, or altering asphericity to impact the optical system. Treatments that affect the visual axis, such as spectacle and contact lens correction, refractive surgeries, corneal onlays and inlays, and intraocular lenses are typically unable to restore......
Angle-to-angle and spur-to-spur distance analysis with high-resolution optical coherence tomography
Eye and Vision - Tập 7 - Trang 1-13 - 2020
To measure angle-to-angle (ATA) and spur-to-spur (STS) distances along six meridians using high-resolution swept-source optical coherence tomography (SS-OCT) and to compare those values with horizontal white-to-white (WTW) distance. 68 eyes from 68 patients were quantitatively assessed with the Anterion SS-OCT (Heidelberg Engineering, Heidelberg, Germany). ATA and STS distances were measured with ......
Age-related changes in geometry and transparency of human crystalline lens revealed by optical signal discontinuity zones in swept-source OCT images
Eye and Vision - Tập 10 - Trang 1-13 - 2023
The shape and microstructure of the human crystalline lens alter with ageing, and this has an effect on the optical properties of the eye. The aim of this study was to characterise the age-related differences in the morphology and transparency of the eye lenses of healthy subjects through the optical signal discontinuity (OSD) zones in optical coherence tomography (OCT) images. We also investigate......
Visual and refractive outcomes after implantation of two models of trifocal intraocular lenses in eyes with previous corneal ablation to treat hyperopia
Eye and Vision - Tập 10 - Trang 1-10 - 2023
To assess whether a trifocal intraocular lens (IOL) with neutral spherical aberration (SA) provides better visual and refractive outcomes than a trifocal IOL with negative SA after hyperopic corneal laser ablation. This is a retrospective comparative study. Patients were classified according to the IOL implanted after cataract or clear lens phacoemulsification [group 1, PhysIOL FineVision Pod-F (n......
Effects of lighting conditions and accommodation on the three-dimensional position of Visian implantable collamer lens
Eye and Vision - Tập 9 - Trang 1-10 - 2022
To investigate the effects of lighting conditions and accommodation on the three-dimensional position of Visian implantable collamer lens (ICL V4c). This observational study recruited 62 eyes of 31 myopia patients underwent ICL V4c implantation. Anterior segment optical coherence tomography (AS-OCT) assessed the anterior chamber depth (ACD), ACD-ICL (distance from the corneal endothelium to anteri......
Metabolomic analysis of aqueous humor reveals potential metabolite biomarkers for differential detection of macular edema
Eye and Vision - Tập 10 - Trang 1-11 - 2023
Macular edema (ME) is a major complication of retinal disease with multiple mechanisms involved in its development. This study aimed to investigate the metabolite profile of aqueous humor (AH) in patients with ME of different etiologies and identify potential metabolite biomarkers for early diagnosis of ME. Samples of AH were collected from 60 patients with ME and 20 age- and sex-matched controls ......
Changes in the posterior corneal surface after femtosecond laser-assisted lenticule intrastromal keratoplasty (LIKE) performed into a pocket (SMI-LIKE) or under a flap (FS-LIKE)
Eye and Vision - Tập 10 Số 1 - Trang 1-10 - 2023
To compare the changes in posterior corneal surface after small-incision lenticule intrastromal keratoplasty (SMI-LIKE) and femtosecond laser-assisted lenticule intrastromal keratoplasty (FS-LIKE) for hyperopia correction. In this prospective comparative randomized study, 23 eyes with hyperopia were recruited. Eyes were categorized into two groups—SMI-LIKE group (11 eyes) and FS-LIKE group (1......
Management of cytomegalovirus corneal endotheliitis
Eye and Vision - Tập 8 - Trang 1-13 - 2021
Cytomegalovirus (CMV) can manifest as corneal endotheliitis in immunocompetent individuals. Early diagnosis is prudent to prevent endothelial cell loss, which could ultimately lead to corneal decompensation. CMV DNA was first detected in an eye with corneal endotheliitis in 2006; since then, clinical evidence from numerous case reports and case series have accumulated. In this narrative review, we......
An interferometric ex vivo study of corneal biomechanics under physiologically representative loading, highlighting the role of the limbus in pressure compensation
Eye and Vision - Tập 7 - Trang 1-11 - 2020
The mechanical properties of the cornea are complex and regionally variable. This paper uses an original method to investigate the biomechanics of the cornea in response to hydrostatic loading over the typical physiological range of intra-ocular pressure (IOP) fluctuations thereby increasing understanding of clinically relevant corneal biomechanical properties and their contributions to the refrac......
