High myopia or high minus power is becoming a rapidly increasing medical and social problem. Permanent power correction is possible today by using laser (LASIK/PRK) or implantable collamer lens (ICL/Phakic IOL). Phakic IOL surgery is a procedure in which a very thin and soft lens is placed inside the eye, which works along with the natural lens of your eye to provide a crisp and clear spectacle free vision. The entire procedure is painless and takes only around 10 minutes.
Cataract surgery in very high myopic eyes can be extremely challenging, more so when there is a previous history of any refractive surgery performed. Our 44 year old patient had a history of two refractive surgeries performed in both his eyes (LASIK around 20 years ago, followed by ICL/Phakic IOL implantation in both eyes 10 years ago due to recurrence of power). Now he had come to us with decreased vision, and on examination, was found to have developed cataract in both his eyes. Additionally, he had a weaker cornea in his right eye, and retinal weakness in both his eyes due to high myopia. A major challenge in these cases was to accurately calculate the power of the intraocular lens to be implanted, which is erroneous with conventional biometry machines. A combination of advanced calculations made with the help of our newest machines, the Tomey OA 2000 optical biometry and the Oculus Pentacam, made this job easy. The ICL explantation and phacoemulsification were performed by our expert team of surgeons, Dr Sneha Batra & Dr Supratik Banerjee. The IOL calculation was once again confirmed by our senior Optometrist Joyashree during the surgery, and finally the correct lens implanted. The happy and satisfied patient achieved a best corrected visual acuity of 6/6p, N6 in both his eyes.
