Angle kappa is the difference between the pupillary and visual axis. This measurement is of
paramount consideration in refractive surgery, as proper centration is required for optimal …

As the number of presbyopia-correcting IOLs and postkeratorefractive patients grows,
continued investigation into relevant preoperative factors and appropriate IOLs is required to …

Background: The angle kappa is important in proper centration of corneal ablation in
keratorefractive surgery. Orbscan II device is widely used preoperatively in photoablation …

Purpose To study the influence of angle kappa (κ) on visual acuity after implantation of a
multifocal intraocular lens (MIOL) and consecutive “touch-up” corneal refractive surgery with …

Purpose To assess the preoperative objective angle alpha and angle kappa measurements
of patients deciding to undergo multifocal refractive lens surgery based on a subjective …

PURPOSE The aim of this cross-sectional study was to obtain the value of mean angle κ in
normal eyes of patients seeking laser vision correction, by the Orbscan 3. METHODS The …

Purpose: To determine the significance of any association between either change in angle
kappa (K) or the rectilinear displacement (L, mm) of the first Purkinje image relative to the …

Purpose: To explore the offset distribution of pupillary centres, the offset between the pupil
centre and the coaxially sighted corneal light reflex (P-Dist) and their correlation in …

Aim: This study aimed to investigate the relationship between photic phenomena and the
kappa angle after trifocal lens implantations. Material and Methods: Fifty eyes of 35 cases …

Background To investigate the change in the distance between corneal apex and pupil
center after small-incision lenticule extraction (SMILE) or implantable collamer lens (ICL) …
