Article Synopsis
- The study aimed to evaluate how astigmatism and higher-order aberrations change after implanting toric intraocular lenses (IOLs) in patients with mild keratoconus and cataracts.
- Preoperative and postoperative visual acuity, astigmatism, and corneal aberrations were measured in 19 patients, showing significant improvements in uncorrected and corrected distance visual acuity after surgery.
- Toric IOL implantation effectively reduced refractive astigmatism, but did not significantly affect corneal astigmatism or higher-order aberrations post-surgery.
Purpose: To investigate the magnitudes and the axis orientations of anterior, posterior, and total central corneal astigmatism in eyes with keratoconus.
Design: Retrospective case series.
Methods: This study comprised 137 eyes of 137 keratoconic patients (97 men and 40 women; mean age ± standard deviation, 36.
Purpose: To investigate the distribution of posterior corneal astigmatism in eyes with with-the-rule (WTR) and against-the-rule (ATR) anterior corneal astigmatism.
Methods: We retrospectively examined six hundred eight eyes of 608 healthy subjects (275 men and 333 women; mean age ± standard deviation, 55.3 ± 20.
Purpose: To assess the changes in intraocular scattering before and after instillation of diquafosol ophthalmic solution in patients with short tear breakup time (TBUT) dry eye.
Methods: We prospectively examined 20 eyes of 20 short TBUT dry eye patients (study group) and age-matched 20 eyes of 20 healthy subjects (control group). Intraocular scattering was measured as the objective scattering index (OSI) at 0.
Purpose: To compare postoperative astigmatic correction between femtosecond lenticule extraction (FLEx) and wavefront-guided LASIK in eyes with myopic astigmatism.
Methods: Fifty-eight eyes of 41 patients undergoing FLEx and 49 eyes of 29 patients undergoing wavefront-guided LASIK to correct myopic astigmatism were examined. Visual acuity, cylindrical refraction, predictability of the astigmatic correction, and astigmatic vector components were compared between groups 6 months after surgery.
Purpose: To evaluate the long-term clinical outcomes and rotational stability of toric intraocular lenses (IOLs) to correct preexisting astigmatism in cataract patients.
Setting: Kitasato University Hospital, Kanagawa, Japan.
Design: Prospective observational study.
Purpose: To investigate the distribution of corneal astigmatism, and the relationship of astigmatism to the patients' age in a large number of pre-cataract surgery patients.
Materials And Method: We retrospectively examined 12428 eyes of 7187 patients (5396 eyes of men, 7032 eyes of women) who underwent cataract surgery at Kitasato University Hospital from April, 2002 to September, 2009. The mean patients' age at the time of surgery was 69.
