Changing trends in keratoplasty in the West of Scotland: a 10-year review

Abstract

Keratoconus was the leading indication for keratoplasty in the West of Scotland. Both anterior LK and endothelial keratoplasty seemed to show an emerging trend as the procedures of choice for dealing with anterior and posterior corneal pathologies, respectively.

Corneal Transplantation Activity Over 7 Years: Changing Trends for Indications, Patient Demographics and Surgical Techniques From the Corneal Transplant Epidemiological Study (CORTES)

“…Although this growth is mainly due to the incidence of EKs, our findings are comparable to data reported by a number of other case series for lamellar keratoplasty [12,29].…”

Prevalence of keratoconus among refractive surgery candidates Abstract: Background: Reasons for refraining from refractive surgery were numerous, with a change of mind after the pre examination being the most common. Patients who changed their minds were very similar to those who had surgery. World Wide Keratoconus is a comparatively common diseases frequency ranging from 50 to 230 per 100,000. Keratoconus is increasing rapidly in Asir Province, Saudi Arabia and more fastly occurred / create complications

“…Environmental factors such as sunshine and hot weather with excessive ultra-violet exposure have been implicated as a contributing factor in the increased prevalence in the Middle East and India.The incidence and severity of keratoconus in Asir Province in Saudi Arabia has been reported to be high with an early onset and rapid progression. 20 The results of this study may imply a relative increased frequency of keratoconus in the Eastern Province in the Saudi population; however, these findings cannot be amply , apply to the general population.…”

An 11-Year Review of Keratoplasty in a Tertiary Referral Center in Turkey: Changing Surgical Techniques for Similar Indications

“…[8][9][10] In the last decade, improved (partial thickness) lamellar keratoplasty (LK) techniques that focused on replacing the diseased layers of the cornea were introduced and implemented widely in developed countries. 1,11 Major advantages of anterior LK over PK are elimination of endothelial allograft rejection with a concomitant reduction in overall graft rejection rates and lower long-term endothelial cell loss of host endothelium. Posterior LK techniques afford much faster visual rehabilitation with less postoperative astigmatism and better anatomical results when compared with PK.…”

“…[1][2][3] Over the last century, indications for corneal transplantation were shaped with respect to geographical location, developmental state of the country, changing demographics and socioeconomic profile of populations, technological advances in ocular surgeries, and patient expectations for a higher quality of life. 1,[3][4][5][6][7] Despite its several drawbacks such as recurrent allograft rejection, postkeratoplasty astigmatism, and endothelial failure, (full thickness) penetrating keratoplasty (PK) has been the method of choice for all keratoplasty indications. [8][9][10] In the last decade, improved (partial thickness) lamellar keratoplasty (LK) techniques that focused on replacing the diseased layers of the cornea were introduced and implemented widely in developed countries.…”
