The First Medennium Phakic Lens implantation in Southeast Asia by the Corneal Expert at Hospital Canselor Tuanku Muhriz, Universiti Kebangsaan Malaysia (UKM)
KUALA LUMPUR: Hospital Canselor Tuanku Muhriz (HCTM), UKM successfully performed the first Medennium Posterior Chamber Phakic Refractive Lens implantation to correct myopia in Southeast Asia on 22 February 2024 by Corneal and Anterior Segment Consultant, Assoc. Prof. Dr. Wan Haslina Wan Abdul Halim from the Department of Ophthalmology, HCTM, UKM. She also served at the UKM Specialist Centre (UKMSC), HCTM, Cheras.
The Medennium Phakic Lens (MPL) implantation was observed by four ophthalmologists consisting of Dr. Dimitrii Dementiev from BLUE Eye Centro, Milano, Italy; Dr. Chan Suet Mei from Ipoh Eye Specialist Centre, Ipoh, Perak; Dr. Tang Seng Fai from OPTIMAX Eye Specialist, Klang, Selangor and Dr. Wan Mohd Hafidz Wan Abdul Rahman from Hospital Tuanku Jaafar, Seremban, Negeri Sembilan. The MPL lenses were sponsored by Aventisin Sdn. Bhd. and were provided by the Medennium company in California, United States.
The Medennium Phakic Lens is a posterior chamber phakic intraocular lens made of medical-grade silicone used to treat myopia patients, which ranges from -6.0 D to -13.0 D. There were two patients involved in the implantation of MPL with a history of high myopia. The first patient is a 41-year-old male with a short-sighted power of -10.50 D for the right eye and -11.125 D for the left eye. The second patient is a 34-year-old male with a short-sighted power of -10.50 D for the right eye and -8.75 D for the left eye. The implantation of MPL was conducted on both eyes of the patients.
The pupil was dilated with mydriatic drops and the procedure of phakic intraocular lens implantation was performed under topical anesthesia. A 2.2 mm temporal clear corneal incision was created as well as 1 or 2 paracentesis. The anterior chamber was filled with ophthalmic viscosurgical devices (OVD), a specialized clear gel to protect the corneal endothelium and other tissues of the eye. The MPL was injected into the anterior chamber using a manufacturer injector cartridge. The haptics of the lens were then tucked under the iris and the OVD was removed. The position of the lens for both eyes was stable and could be left in place to function.
During follow-up on day 1, the patients reported improvement in their vision without needing to wear their usual glasses. There was no complication recorded and the patients are very satisfied with the lens implantation as being independent from spectacles. The post-operative follow-ups will be conducted in 1 month to monitor the progression of both patients.
