COMPARING KAMRA AND RAINDROP:

There are many different techniques in which the eyes can be improved in order to cure presbyopia. This is a condition that most adults have which inhibits them to read and for which they have to purchase a pair of reading glasses. Adults can undergo a small surgery that allows them to overcome this problem and it is called corneal inlay surgery. There are different types of corneal inlay surgery, but karma and raindrop are the most popular. The question remains: which one should you undergo when you decide to have the corneal inlay surgery?

Kamra Corneal Inlay

The Karma Corneal Inlay surgery was the very first corneal inlay procedure to gain acceptance and credibility from the FDA. It is mainly performed in the USA, but since its first procedure, it has expanded to over 50 different countries worldwide. The purpose of this surgery is to reduce the need for reading glasses in adults who can see far but struggle to see objects up close.

The Kamra inlay is small and thin – it is about 3.8mm in diameter which is the quarter of the size of a contact lens, and it is 6 microns thick, which is thinner than a strand of human hair. When the inlay is implanted, it is positioned so that the centre opening is directly in front of the pupil of the eye. It creates a ‘pinhole camera effect’ that expands to clear your vision when it comes to the closer objects. This inlay is typically implanted in the non-dominant eye which allows both eyes to see whilst improving near vision. It can be performed in a surgeon’s rooms and only takes about 15 minutes for the inlay to be implanted. There are no stitches needed and healing time will vary from person to person.

In 2016 the Raindrop inlay was approved by the FDA in order to treat presbyopia in adults. This inlay has the same purpose as the Kamra inlay, but it is almost a more evolved method. The inlay is about 2mm in diameter and is made of a hydrogel that is similar to the material used to make soft contact lenses. The lens is almost identical to the human cornea and has optical characteristics that make it unique in its own right.

The Raindrop inlay is implanted in the non-dominant eye, much as the Kamra inlay, through a laser-cut flap in the cornea. As soon as it is in position, the inlay changes and adapts to the curvature of the cornea so that the eye acts like a multifocal contact lens. The lens does not need any further repositioning as soon as it has been implanted and people have noticed improvement within 6 months of the surgery. Two years after surgery, 90% of patients found that their vision had been restored to an almost perfect eyesight.
