Poor visual acuity after big bubble DALK linked to elongated posterior segment
Poor visual outcomes after big bubble deep anterior lamellar keratoplasty may be attributable to large vitreous length, higher-order aberrations and surgical interface haze, according to a study. “Our results reflect the fact that differences in postoperative visual acuity are independent of corneal features and show that the main factor that contributed to decreases in [best corrected visual acuity] was an elongated posterior segment,” the study authors said.
