Introduction
Keratoconus is a progressive disease of the cornea that usually
begins at puberty and progressively causes reduction of quantity and
quality of visual acuity and ocular discomfort and poor Visual acuity
when corrected with spectacles or ill ftting contact lenses. Gradual
reduction in quantity and quality of visual acuity in these young
adults who have so far lead an active life style can lead to mental
stress. Contact lenses play a vital role in restoration of visual function.
The patient visiting an ophthalmologist is commonly recommended
surgical procedure options like interstromal rings, cross linking and
penetrating keratoplasty. Quality of life despite satisfactory results on
visual outcome measures obtained after PK remains impaired.

Most
of these patients have to still wear contact lenses after such treatments.
Non availability of good rigid contact lens ftters is one reason reason
of letting patient continue with speactacles which provide just
manageable quality and quantity of vision.
Only a few studies have so far been conducted to estimate the
incidence and prevalence of the condition, and, although the incidence
varies somewhat from to country to country, a 1986 population-based
study in the US indicated that approximately 5 in 10,000 people
have Keratoconus. Similarly, a study in Central India indicated
prevalence as 0.0003%-2.3.

Keratoconus is caused by a combination
of genetic and environmental factors. The exact contribution of each
to the aetiology is as yet unknown. Keratoconus afects both genders,
although it is unclear whether signifcant diferences between males
and females exist.

As the prevalence of keratoconus is low, many
public health policy makers view the disease as a minor concern
when contrasted with eye diseases such as glaucoma and age-related
macular degeneration.

However the concerns are severe because
this disorder has onset only in young adults and disability sets in age
that efects their education and career. The progression of disorder
further leads to poor unided visual acuity and stress to the patient.

Abstract
Aim of the Study: To analyse the mental health status and psychological well being of the
keratoconus patients using rigid contact lenses compared to spectacle corrected ones. The
objective is to study if the correcting vision with contact lenses impacts the mental health
status of the patients sufering from keratoconus.
Methodology: In the month of January to April, 2015 a cross sectional study was conducted
in Ahooja eye hospital, Gurgaon, Haryana, India and Rajan eye care hospital, Tnagar,
Chennai, Tamilnadu, India. Thirty two keratoconus patients were enrolled for the study
and subjects were asked to the mental health status questionnaire MHI 38 with informed
consent. Fifteen were habitual contact lens wearers and seventeen non contact lens wearers
who volunteered to participate this study. Study included those contact lens users who wore
lenses all waking hours and had been wearing them for atleast one year. All the questions
were score coded for entering the data in Microsoft Excel sheet. The status of mental health
was based on eight indicises which provided information on mental well being.
Results: 17 males and 15 females participated in this study. The mean age of the participant
was 28.03± 5.56 (range 20-39 years). The mean score of keratoconus patients of non
contact lens wearer and contact lens wearer in Anxiety was 32.84 ± 2.99 &18.79 ± 3.67,
Depression 13.34 ± 4.08 & 7.71 ± 2.19, Loss of behavioural / Emotion Control 30.29 ± 2.22
& 22.77 ± 6.70, General Positive Afect 49.00 ± 3.86 & 29.73 ± 4.48, Emotion Ties 10.17
± 1.44 & 5.28 ± 1.71, Life Satisfaction 3.44 ± 0.96 & 4.94 ± 0.73, Psychological Distress
81.28 ± 4.48 & 53.15 ± 9.62, Psychological Well Being 41.15 ± 4.75 & 69.08 ± 5.26,
Mental Health Index 119.81 ± 5.53 & 185.82 ± 11.03 respectively. Our results show that P
value is <0.05 is statistically signifcant in all subscales and on the global scale variable of
MHI 38. It suggests those who wear contact lenses have signifcantly better life satisfaction
and Mental Health. Proper contact lens option as vision correction in Keratoconus patients
improves the mental health status and are more positive in attitude compared to non users.
A successful contact lens ft infuences the mental health status compared to those who do
not opt to wear it.
Conclusion: Eye care practitioners should motivate and proactively advise contact lenses
to patients with Keratoconus as they will have better life satisfaction and psychological
well being.
