Purpose: To describe a femtosecond laser-assisted small incision sutureless intrastromal lamellar keratoplasty in an eye with severe keratoconus and report on the outcome with a 1-year follow-up.
Methods: A 20-year-old man with a history of keratoconus presented for evaluation at the Tilganga Institute of Ophthalmology, Kathmandu, Nepal. The patient had previously undergone a deep anterior lamellar keratoplasty in the left eye.
Purpose: To evaluate visual and refractive outcomes of small incision lenticule extraction (SMILE) for hyperopia.
Methods: This was a prospective study of vertex-centered hyperopic SMILE using the VisuMax femtosecond laser (Carl Zeiss Meditec, Jena, Germany). Inclusion criteria were maximum attempted hyperopic meridian of between +1.
Purpose: To evaluate visual and refractive outcomes of small incision lenticule extraction (SMILE) for hyperopia.
Methods: This prospective study of vertex-centered hyperopic SMILE used the VisuMax femtosecond laser (Carl Zeiss Meditec, Jena, Germany). Inclusion criteria were maximum attempted hyperopic meridian of between +1.
Significance: Existing patient-reported outcome instruments in refractive error are paper-based questionnaires. They are not comprehensive and psychometrically robust. This study has identified the content of the refractive error-specific item banks that aim to provide comprehensive and scientific measurement of refractive error-specific quality of life.

Methods: Participants were recruited from Tilganga Institute of Ophthalmology and Dhulikhel Hospital, Nepal. Semi-structured in-depth interviews were conducted with 101 people with refractive error.
Purpose: To evaluate optical zone diameter efficacy and spherical aberration change in hyperopic small incision lenticule extraction (SMILE).
Methods: Prospective study of 60 consecutive hyperopic SMILE procedures using the VisuMax femtosecond laser (Carl Zeiss Meditec, Jena, Germany) and matched LASIK procedures with the VisuMax and MEL 80 excimer (Carl Zeiss Meditec) lasers. Inclusion criteria were maximum attempted hyperopic meridian of between +1.
Background: Nanophthalmos is an uncommon developmental ocular disorder characterized by a small eye with short axial length, high hyperopia and high lens to eye volume ratio due to arrested development of the globe in all directions. Different types of fundus changes can rarely occur with nanophthalmos.
Observations: This is a case report of a 17 years old female who presented with bilateral gradual progressive visual loss and photophobia at Tilganga Institute of Ophthalmology on 3rd July 2015.
Purpose: To evaluate optical zone centration of hyperopic small incision lenticule extraction (SMILE).
Methods: This prospective study of 60 consecutive hyperopic SMILE procedures used the VisuMax femtosecond laser and matched LASIK procedures with the VisuMax and MEL 80 excimer lasers (Carl Zeiss Meditec AG, Jena, Germany). Inclusion criteria were maximum attempted hyperopic meridian of between +1.
Purpose: To evaluate the outcomes of small-incision lenticule extraction for myopia using the Visumax femtosecond laser at the first refractive surgery unit in Nepal during the first 30 months of operation.
Setting: Tilganga Institute of Ophthalmology, Kathmandu, Nepal.
Design: Retrospective noncomparative case series.
