Analysis of zonular-free zone and lens size in relation to vial length of eye with age

Abstract

When choosing an intraocular lens, one should consider the patient's age and the A-P globe length. Six eyes (5%) showed unusual anterior insertion of zonular attachment, which reminds us to be prudent with a large paracentral capsulorhexis.

Rotational stability of a toric intraocular lens: Influence of axial length and alignment in the capsular bag

“…2 Studies show that capsular bag diameter tends to correlate with an increase in AL. [15][16][17] Thus, early rotation is more likely to occur in highly myopic eyes. Patel et al 6 used serial digital photography to compare rotation between plate-haptic IOLs and loop-haptic IOLs.…”

Hyperopic shift from posterior migration of hydrophilic acrylic intraocular lens optic

“…The series is too small to confirm whether certain patient groups are at risk, although the 2 cases with phimosis had retinitis pigmentosa, which is associated with aggressive capsule fibrosis, and axial myopia in which there is a relatively large capsular bag. 6,7 The phenomenon of delayed hyperopic shift following cataract surgery has been described after implantation of a single-piece Collamer plate-haptic IOL (CC420BF, Staar Surgical Co.) with a minimum incidence of 0.02%. 8,9 With this IOL, the mean hyperopic shift in affected cases was 1.81 D (range 0.25 to 3.75 D) occurring between 1 week and 11 months after surgery.…”

Human ocular biometry

“…Globe dimensions were found in articles by Ehlers (1968), Harayama et al (1980), Huang (1987) and Lim et al (1998). Corneal dimensions came from al-Umran and Pandolfi (1992), Denis et al (1998), Ehlers (1968), Harayama et al (1980), Huang (1987), Kirwan et al (2005), Ko et al (2001), Kwak et al (1988), Liu (1992), Rufer et al (2005) and Savini et al (2011).…”
