Background: Cataract surgery is a very common intervention. The objective of this study was to investigate the trends in the number of cataract surgeries in Norway and the characteristics of patients who underwent cataract surgery in the period 2010-19., Material and Method: Data on cataract surgery were collected from the Norwegian Patient Registry. The number of cataract surgeries per million inhabitants was calculated on the basis of population data from Statistics Norway., Results: The number of cataract surgeries in Norway increased from 36 340 in 2010 to 48 291 in 2019. This corresponded to an increase of 21 %, from 7 480 to 9 063 per million inhabitants respectively, in the same period. The average age was 74 years, and more than 90 % of the patients were above the age of 60. The proportion of cataract surgeries among patients older than 60 years remained virtually unchanged through the study period. Women accounted for 60 % of the cataract surgeries in 2010 and 57 % in 2019. The proportion of surgeries performed by contract specialists in the entire period varied from 32 % in Central Norway Regional Health Authority to 62 % in Northern Norway Regional Health Authority., Interpretation: The number of cataract surgeries increased throughout the period in pace with the population growth in the age group above 60 years. With further population growth and an increasing number of older people, planning for a further increase in the number of cataract surgeries in future years is likely to be required.

Background: Cataract surgery with implantation of an artificial intraocular lens (IOL) in the lens capsule ('in-the-bag') is one of the world's most common surgeries. After many years, this IOL capsule complex may dislocate. This condition, called late in-the-bag IOL dislocation, has an estimated incidence of 0.5-1 %, with increasing frequency., Case Presentation: A man in his late seventies presented with monocular decreased vision and high intraocular pressure. Pupil dilation revealed the diagnosis of late in-the-bag IOL dislocation. Surgery was performed with repositioning of the dislocated complex by scleral suturing. The patient's visual acuity normalised after surgery., Interpretation: Late in-the-bag IOL dislocation is no longer a rare condition. It requires surgery, which may be performed either as repositioning of the dislocated complex or by exchanging it for a new IOL. Both operation methods give a good visual outcome.

Background: Eye banks have procured, processed and stored donor corneas for decades. In parallel, new techniques have emerged employing allogeneic transplantation of various cells and tissues from the eye banks. This progress is a consequence of increased knowledge of stem cells, cell kinetics and immunological aspects and improved techniques for cell culturing, tissue storage and microsurgery., Material and Methods: Review article on available transplants for treating eye diseases, based on experience with eye banking, clinical ophthalmological practice, own research and literature retrieved from PubMed, Medline and www.google.com., Results and Interpretation: Treatment techniques for eye diseases, which require biological material for grafting, need efficient eye banks for continuous supply of donor material of high quality. New Norwegian legislation, based on implementation of EU Directive 2004/23/EC, demands authorization of all eye banks. The EU Directive sets high and rigorous standards for quality and safety for donation, procurement, testing, processing, storage and distribution of tissues and cells. Well-run eye banks are of great importance for modern treatment of patients suffering from eye diseases and for progress and research in ophthalmology.
