Article Synopsis
- The study aimed to explore the impact of cylinder axis-flip after the implantation of toric intraocular lenses (TIOLs) on vision and patient-reported outcomes in a teaching hospital in the UK.
- In a post hoc analysis of data from a randomized study, it was found that 34.5% of the eyes experienced axis-flip, but there were no significant differences in visual acuity or quality-of-life scores between the flipped and unflipped cases.
- The results suggest that axis-flip had no negative effects on vision or patient outcomes, and adjusting for posterior corneal astigmatism may have helped reduce instances of axis-flip in some patients.
Aim: To evaluate corneal astigmatic outcomes of femtosecond laser-assisted arcuate keratotomies (FAKs) combined with femtosecond-laser assisted cataract surgery (FLACS) over 12mo follow-up.
Methods: Totally 145 patients with bilateral cataracts and no ocular co-morbidities were recruited to a single-centre, single-masked, prospective randomized controlled trial (RCT) comparing two monofocal hydrophobic acrylic intraocular lenses. Eyes with corneal astigmatism (CA) of >0.

Here, the first soft x-ray second harmonic generation (SXR SHG) interfacial spectrum of a buried interface (boron-Parylene N) is reported. SXR SHG shows distinct spectral features that are not observed in x-ray absorption spectra, demonstrating its extraordinary interfacial sensitivity.

Methods: Optical design and analysis was performed with customized optical design software. Nine patients with implanted OOKP devices and 9 age-matched control patients were assessed.
The osteo-odonto-keratoprosthesis (OOKP), although described over 40 years ago, remains the keratoprosthesis of choice for end-stage corneal blindness not amenable to penetrating keratoplasty. It is particularly resilient to a hostile environment such as the dry keratinized eye resulting from severe Stevens-Johnson syndrome, ocular cicatricial pemphigoid, trachoma, and chemical injury. Its rigid optical cylinder gives excellent image resolution and quality.
