Currently, they focus on surgical techniques with available pIOLs like Kelman
Duet pIOLs, which are being widely used. These pIOLs are not foldable. However,
it consists of two components, viz: optic and haptic. To facilitate and manipulate the
components, cornea visions of two, with one mm clear, are created at various angles.
Sequentially a small incision was inserted and assembled over the anterior chamber.
Initially, the haptic is first inserted by forceps with one incision to reposition at a
certain angle. Further, the optic is being injected over the anterior chamber with a
3 mm incision. Implantable Collamer Lenses (ICLs) are widely used as post chamber
pIOLs. These ICLs are mainly incorporated with a material known as ‘collamers,’
which has increased biocompatibility. Collamers mainly consist of 60% hydroxyethyl
methacrylate copolymer and 0.2% collagen, respectively. This material will inhibit
the aqueous protein binding and the deposition of the monolayer, being attracted to
fibronectin of IOL surfaces [44, 45].
3.2 Cosmetic Implants
Cosmetic implants are often referred to as prosthetic devices on which an attempt
is made with an acceptable aesthetic norm to bring some portion of the body back
to its position. Follow-up mastectomy (due to breast cancer) is commonly used for
correcting out the forms of disfigurement, and it’s modifying aspects present in the
body. In order to improve the appearance, numerous plastic surgery techniques are
developed for various types of cosmetic implants and restore its original function
inside the body. Examples include the pectoral implant, injectable gluteal fillers,
ocular prosthesis, nose prosthesis, and breast implants. Recently various types of
cosmetic implants have been developed with various types of plastic surgery techniques for the appearance or restoring the function on the human body with further
additional techniques. Pectoral implants (Male chest enhancement) are increasingly
performed with men. Most of the patients are unable to do proper exercises to build up
their pectoral muscles. So, it is generally performed with fewer numbers of patients
initially with their chest wall of acquired or congenital deformities. E.g. pectoral
denervation because of plexus injury, absence of unilateral or congenital pectoral
muscles, post-surgical chest walls deformities, muscle-related injuries due to sports
events, etc. For a specific patient, customized pectoral implants are typically made
by various manufactures. Depending upon the deformity of defects, these pectoral
implants are placed either in an oblique or transverse position. Generally, these
pectoral implants are usually made up of silicone rubber of soft pliable consistency,
which can be customized easily. Also, it is typically of a variable with CT appearance
with denser soft tissue less dense than that of bone.
Gluteal augmentation (gluteal fillers) was found in 1965 and one of the very
fastest-growing plastic surgery techniques. It mainly involves with prostheses insertion in the parts of breast and buttocks. Various techniques are performed, which
include autogenous fat augmentation, solid silicone implant replacement, and filler
injection. It can be seen that for the buttock augmentation, FDA has approved the
