Central and Peripheral Ocular High-Order Aberrations and Their Relationship with Accommodation and Refractive Error: A Review.

High-order aberrations (HOAs) are optical defects that degrade the image quality. They change with factors such as pupil diameter, age, and accommodation. The changes in optical aberrations during accommodation are mainly due to lens shape and position changes.

Contrast sensitivity function with soft contact lens wear.

Purposes: To compare contrast sensitivity function (CSF) with soft contact lens (SCL) and spectacles wear. To investigate the effect of a three-month period of SCL wear on CSF.

Methods: Forty-seven myopic subjects with no history of contact lens (CL) wear were included in this longitudinal prospective study.

Daily versus monthly disposable contact lens: Which is better for ocular surface physiology and comfort?

Purpose: To investigate the effect of soft contact lenses (SCL) wearing modality and lens materials on the changes in conjunctival bulbar and limbal redness and conjunctival and corneal staining after two months of SCL wear. Comfort level was also analyzed.

Methods: In this longitudinal clinical trial, forty-seven neophyte myopic subjects were fitted with a monthly disposable lens (lotrafilcon-B or comfilcon-A or balafilcon-A) in one eye and a daily disposable lens (nelfilcon-A or stenofilcon-A or nesofilcon-A) in the other eye, randomly selected.

Causes of low vision and major low-vision devices prescribed in the low-vision clinic of Nepal Eye Hospital, Nepal.

Visual impairment is a major public health problem. Identifying the main causes of low vision and the major low-vision devices prescribed will help to develop and implement the low-vision rehabilitation service. We find out the causes of low vision and the low-vision devices prescribed in the low-vision clinic of Nepal Eye Hospital.

Effect of three months of soft contact lens wear on conjunctival cytology.

Background: The purpose of this study was to investigate the effect of three months of soft contact lens wear on conjunctival goblet cell density and epithelial cell morphology.

Methods: This was a longitudinal clinical trial. Conjunctival impression cytology was performed on the superior palpebral conjunctiva in fifty-four eyes of twenty-seven neophyte contact lens wearers before and after three months of contact lens wear.

Level of compliance in contact lens wearing medical doctors in Nepal.

Purposes: To determine the level of compliance and major non-compliant behaviors in contact lens (CL) wearing medical doctors (MDs) and to compare it with age matched CL wearing normal subjects with no medical background (NS).

Methods: Thirty-nine current CL wearing MDs, who were prescribed CLs in Nepal Eye Hospital, Kathmandu, Nepal, between 2007 and 2011, were interviewed on ten modifiable compliant behaviors regarding lens care and maintenance. The level of compliance and the rate of non-compliance for each behavior were determined and compared with NS.

Goblet cell density association with tear function and ocular surface physiology.

Purpose: To determine the relationship of goblet cell density (GCD) with tear function and ocular surface physiology.

Methods: This was a cross-sectional study conducted in 35 asymptomatic subjects with mean age 23.8±3.

Common symptoms of Nepalese soft contact lens wearers: A pilot study.

Aim: To determine the common symptoms in current soft contact lens (CL) wearers and their association with other factors among Nepalese population.

Methods: All the current CL wearers who started to wear soft CL in Nepal Eye Hospital between July 2007 and June 2012 were invited for the participation. Frequency of the ten most common symptoms, divided into never, occasionally, frequently and consistent were recorded.

Intraocular pressure measurement with ocular response analyzer over soft contact lens.

Purpose: To compare intraocular pressure (IOP) measured with ocular response analyzer (ORA) with and without soft contact lenses (CL) on eye.

Methods: Goldmann correlated intraocular pressure (IOPg) and corneal compensated intraocular pressure (IOPcc) were measured in 56 eyes of 28 subjects without any ocular pathology, using ORA. One eye was fitted with Narafilcon A (1-Day Acuvue True Eye, Johnson & Johnson) and the other eye with Nelfilcon A (Daily AquaComfort Plus, Ciba Vision), each with -3.

A retrospective analysis of children with anisometropic amblyopia in Nepal.

Purpose: Anisometropia is one of the main causes of amblyopia. This study was conducted to investigate the association between the depth of amblyopia and the magnitude of anisometropia.

Methods: A retrospective record review was conducted at the Nepal Eye Hospital between July 2006 and June 2011.

Microbial contamination of contact lens care accessories and compliance with care regimens in Nepal.

Purpose: To determine the rates of microbial contamination and identify contaminants associated with contact lens (CL) care accessories. To investigate self-reported compliance levels with care of CL accessories and its association with contamination level.

Methods: A total of 46 CL cases and care solutions from asymptomatic soft contact lens wearers were collected.

Ocular complications of soft contact lens wearers in a tertiary eye care centre of Nepal.

Aim: To determine the prevalence and the major types of ocular complications related with soft contact lenses (CL) in a tertiary eye care centre of Nepal.

Methods: Medical files of 4064 soft CL wearers who started wearing CL between January 2003 and December 2010 in BP Koirala Lions Centre for Ophthalmic Studies (BPKLCOS) Kathmandu, Nepal, were retrospectively reviewed. Records of patients who visited the hospital with complications were analyzed.

Visual status of Nepalese national football and cricket players.

This study was undertaken to assess the visual acuity, refractive status, stereopsis, colour vision and ocular morbidity of Nepalese national footballers and cricketers. Ninety-five national football and cricket players of different age group, who had at least played one international tournament representing Nepal, were included in the study. A thorough ocular examination of the players was done in the study period of six months, which revealed that higher-level professional players have significant visual problems.
