Article Abstract
Objective: To compare the difference in performance between the image-guided alignment system and the manual-marking method in the four-haptic hydrophobic monofocal toric intraocular lens (IOL).
Methods: Medical records of patients who underwent cataract surgery with a four-haptic hydrophobic monofocal toric IOL implantation between May 2020 and April 2021 and with 3-month visit data available were investigated. Toric IOL misalignment, residual astigmatism, and mean prediction errors between the two groups were compared.
Results: This study included 49 eyes of 44 patients (women: 68%; mean age: 67.2±7.0 [range: 47-82] years). Twenty-nine eyes of 26 patients were treated with toric IOL implantation using the image-guided system and 20 eyes of 18 patients were treated using the manual-marking method. No statistical differences were observed regarding the baseline characteristics of the two groups. Three months after the surgery, the misalignment of the toric IOL was significantly lower in the image-guided group (2.18°±0.65°, range: 1.26°-3.95°) than in the manual; marking group (4.72°±0.74°, range: 3.44°-6.21°; P <0.001).
Conclusion: In comparison to the manual-marking method, the image-guided system reduced the misalignment of a four-haptic hydrophobic monofocal toric IOL.
Purpose: To explore the significance of changes in anterior chamber depth (ΔACD) and astigmatism between 4 and 8 weeks following uneventful phacoemulsification.
Patients And Methods: Anterior chamber depth (ACD, mm), autorefractometry and subjective refraction were monitored in pseudophakic eyes implanted with non-toric IOLs (group 1, SA60AT, n=36; group 2, SN60WF, n=34; group 3, ICBOO, n=16) and phakic control group (n=30, group 4a, for ACD and autorefractometry) over four weeks. Changes in subjective refractions were compared with repeatability in normal phakic eyes (n=30, group 4b).
Phacoemulsification and intraocular lens (IOL) implantation comprise a standard procedure for cataract treatment. However, minimal refractive error remains a determinant of postoperative results. Our study aimed to evaluate the refractive outcomes and the impact of the surgeon's experience and the IOL model on Kosovan and Hungarian patients after cataract surgery.
Purpose: Accurate alignment of Toric Intraocular Lens (T-IOLs) in cataract surgery is crucial for good visual outcomes. The purpose of this study was to evaluate the influence of rotation, axial shift and their combined effects on the refractive error and image quality of a wide range of T-IOL powers (from +1.50 D to +6.
Purpose: This study aimed to evaluate one-year clinical outcomes in cataract patients with pre-existing corneal astigmatism implanted with a biconvex aspheric toric monofocal intraocular lens (IOL) with a double C-loop haptic-design.
Methods: One hundred and eighteen patients (236 eyes) with corneal astigmatism (≥0.75D) were implanted bilaterally with the PODEYE toric IOL and assessed up to 1-year after surgery.
Purpose: To evaluate visual outcomes and patient satisfaction at far and intermediate distances, up to 3 months postoperatively, in patients implanted with a hydrophobic acrylic intraocular lens (IOL) using a manual delivery system.
Methods: This was a prospective single-arm study of visual outcomes and patient satisfaction after successful bilateral cataract surgery with the Clareon monofocal and monofocal toric IOL using the Monarch IV delivery system. Endpoints included bilateral visual acuity, manifest refraction, and satisfaction assessed at 1 and 3 months post-operatively, as well as a surgeon survey of in-the-bag placement and satisfaction.
