Corneal Topographers Market -
Market Dynamics
Increasing number of population
facing cataract related eye problem and refractive error is a major factor
contributing to significant growth of Corneal
Topographer Market. Moreover, the market is expected to witness positive
growth with high prevalence of cataract and refractive error diseases
worldwide, as corneal topographer is important imaging device to evaluate pre and
post cataract and refractive error surgery.
According to the 2017 factsheet
by World Health Organization (WHO), around 253 million people worldwide suffer
from vision impairment, 36 million are blind, and 217 million have moderate to
severe vision impairment. Moreover, the statistics indicate that refractive
errors are the first cause of visual impairment and the second cause of visual
loss worldwide, as 43% of visual impairments are attributed to refractive
errors.
Moreover, international and
national efforts to increase awareness about cataract would help improve
cataract surgeries thereby increased use of corneal topographer, World Health
Organization (WHO) and Task Force of International NGO have jointly prepared and
launched a common agenda for global action called ‘The Vision 2020- the right
to sight’ in 1999 with aim to eliminate blindness worldwide by 2020.
However, complications and
post-surgery errors observed with LASIK surgeries to correct refractive error may
deter the market growth. According to a report by the U.S Food and Drug
Administration (FAD), 2017, 45% of refractive error surgeries observe some form
of error. Moreover, some clinicians prefer other technique such as optical
biometry, pachymetry over corneal topography, which further may limit growth of
the corneal topographer market.
Corneal topographer is a
non-invasive imaging device that allows mapping and examination of the corneal
surface. Topographer provides detailed description of various curvature and
shape characteristics of cornea. Mapping the topography of cornea is important
for assessing quality of vision as refractive power of the eye significantly
depends on cornea and overall corneal health.

Corneal topography with
topographers is used in cataract surgery (to study post-surgery astigmatism),
in refractive surgery such as LASIK (to screen candidates for normal corneal
shape, patterns and ruling out suspicious or keratoconic patterns) or in assessing
contact lenses fitting. Moreover, it helps in determining the suspect of the
Keratoconus (intraocular pressure imparts the cone shape to cornea), incision
placement and intrastromal ring placement in keratoconus, and to study and
diagnose corneal and ocular surface disorders such as pterygium, limbal
dermoid, and localized corneal scars. Topographer thus, plays an important role
in diagnosing and treating major eye diseases related with cornea.

Regional Insights
On the basis of Geography,
corneal topographers market is segmented into North America, Latin America,
Europe, Asia Pacific, Middle East, and Africa. North America is expected to
hold dominant position in the corneal topographers market during forecast
period. The U.S. has one of highest population of contact lens users in the
world. According to Centre for Disease Control and Prevention (CDC) in 2017,
around 45 million people in the U.S. wear contact lenses. The average age of
contact lens wearers in the U.S. is 31 years. Corneal topographers would be of
maximum utility for ophthalmologist and optician with such high user base for
contact lens, which in turn is expected to boost growth of the corneal topographers
market in the region.
Moreover, high preference for
LASIK surgeries to correct nearsightedness and farsightedness is expected to
propel growth of the market. This is owing to use corneal topographer in LASIK
surgeries to evaluate the extent to which corneal changes are required to be
done, with the help of topographic map of cornea. According to statistics by
National Eye Institute in 2010, Astigmatism— the root cause for refractive
errors, affects around 1 in every 3 people and may occur in combination with
near- or farsightedness.

Asia Pacific is expected to
witness a positive market growth, owing to high number of cataract patients and
proportionate rise in cataract surgeries. According study published in Advanced
Medical and Health Research in 2015, overall prevalence of blindness is 1.1%,
the principal cause for this blindness is cataract (62.6%) which affects over 9
million people.
Corneal Topographers Market -
Competitive Landscape
Key players operating in the
corneal topographers Market include, Alcon plc., Abbott Laboratories, Topcon
Corporation, Allergan, Inc., Essilor International SA, Bausch Health Companies,
Inc., Valeant Pharmaceuticals International, Inc., STAAR Surgical Company,
NIDEK Co., Ltd., and Carl Zeiss Meditec, Inc.
Key players are focused on
launching novel topographers that are designed to use with specific application
such as cataract surgery, contact lens fitting. Moreover, products that combine
corneal topography with optical biometry, pachymetry and techniques for
comprehensively measuring and assessing corneal surface are being developed.
For instance,
In November 2017, Johnson and
Johnson Vision granted with FDA approval for iDESIGN System for LASIK, for
treatment of hyperopia – with and without astigmatism. The iDESIGN System
requires less time for procedures as it can capture five different measurements
such as wavefront aberrometry, wavefront refraction, corneal topography,
keratometry, and pupillometry in a single capture sequence.
In January 2017, Topcon Medical
System’s Aladdin Biometer with corneal topographer HW3.0 was granted with FDA
approval for distribution in the U.S. New version of this topographic system
consists of lens thickness, central pachymetry, and a generic toric IOL
calculator that expands the capabilities of the device.
In 2016, Bausch + Lomb,
introduced the ORBSCAN 3 anterior segment analyzer, which is the third
generation of the multidimensional ORBSCAN topographer.
