Purpose: To compare long-term intraocular lens (IOL) decentration and tilt following femtosecond laser-assisted cataract surgery (FLACS) and conventional surgery using swept-source anterior segment ocular coherence tomography (SS-ASOCT).
Methods: In this retrospective cross-sectional study, all patients underwent FLACS or conventional cataract surgery. Those with a minimum of 12-months follow-up since surgery were included.

The iris is a unique structure, with exquisite variations in colour and form. Pathological changes, specifically including iris cysts and tumours are relatively uncommon, difficult to diagnose, and yet potentially blinding or life-threatening. Based on a comprehensive literature review, with highly illustrated key case examples, this report aims to guide the clinician in filtering the differential diagnoses of iris cysts and tumours.

Methods: Statistical analysis of the New Zealand National Eye Bank's prospective database of all keratoplasties was performed between January 1991 and January 2020. Indications for keratoplasty were isolated for the primary diagnosis.
Importance: Reduction of intraoperative complications in phacoemulsification cataract surgery.
Background: To assess practicability of a risk stratification system, the New Zealand Cataract Risk Stratification (NZCRS) system, in a major teaching hospital service, without investigator oversight, to ascertain whether benefits identified in research studies are maintained in busy clinical practice.
Design: Prospective cohort study in a major public teaching hospital.
Purpose: To assess intraoperative complications of phacoemulsification surgery in public teaching hospital settings using modified preoperative risk stratification systems.
Design: Prospective cohort study.
Methods: Preoperative risk stratification of 500 consecutive cataract cases using the New Zealand Cataract Risk Stratification (NZCRS) scoring system.
Purpose: To assess the effect of preoperative risk stratification for phacoemulsification surgery on intraoperative complications in a teaching hospital.
Design: Prospective cohort study.
Methods: Prospective assessment of consecutive phacoemulsification cases (N = 500) enabled calculation of a risk score (M-score of 0-8) using a risk stratification system.

We describe 7 cases in which supplementary sulcus-based toric intraocular lenses (IOLs) rotated postoperatively, requiring surgical realignment. The initial rotation was identified clinically between 3 months and 36 months postoperatively. All eyes had keratoconus, with and without prior keratoplasty, and 6 had longer than average axial lengths.

Methods: Retrospective clinical record review at a single New Zealand tertiary referral centre. A total of 182 eyes that underwent a vitrectomy for a diabetic vitreous haemorrhage and/or tractional retinal detachment between March 2000 and December 2010 were included.
Importance: A contemporary benchmark for the most common ophthalmic surgery.
Background: To assess patient characteristics and outcomes of contemporary phacoemulsification cataract surgery in a New Zealand public teaching hospital setting.
Design: Prospective observational study.

Purpose: To evaluate 2 preoperative risk stratification systems for assessing the risk of complications in phacoemulsification cataract surgery, performed by residents, fellows, and attending physicians in a public teaching hospital.
Design: Cohort study.
Methods: One observer assessed the clinical data of 500 consecutive cases, prior to phacoemulsification cataract surgery performed between April and June 2015 at Greenlane Clinical Centre, Auckland, New Zealand.
Aims: To report the 25-year longitudinal trends in indications and corneal transplantation techniques in New Zealand.
Methods: Statistical analysis of prospectively acquired New Zealand National Eye Bank (NZNEB) electronic database from 1991 to 2015 inclusive. Subjects were recipients of corneal transplants in 62 centres supplied by the NZNEB.
Purpose: To analyze corneal haze after corneal collagen crosslinking (CXL) for progressive keratoconus using Scheimpflug densitometry.
Setting: Auckland District Health Board, Auckland, New Zealand.
Design: Prospective randomized controlled study.

Unlabelled: We highlight potential problems and pitfalls in cases of Salzmann nodular degeneration by reporting the case of an 84-year-old man with reduced visual acuity due to particularly extensive bilateral Salzmann nodules and moderate cataracts. Large annular Salzmann lesions were removed by superficial keratectomy in each eye. The reproducibility and accuracy of keratometry and biometry improved significantly, and uneventful phacoemulsification cataract surgery was performed 4 weeks after the keratectomy.

A 2-hit hypothesis proposes an underlying genetic predisposition coupled with external environmental factors, including eye rubbing and atopy. The variable prevalence and natural history have been better defined including significant cone progression in middle age.
