To evaluate the Refractive Hydrophilic Acrylic multifocal RAYNER IOLs in terms of safety and post op results stressing on improvement in quality of vision after cataract surgery and compatibility with other eye having its own crystalline lens, monofocal IOL or multifocal IOL.
WAPDA Teaching Hospital Complex and Acuity Eye Center Lahore Pakistan.
Prospective study was planned. 50 eyes 0f 45 patients with the diagnosis of cataract and no other co morbid ocular pathology were included in the study. Refractive Hydrophilic Acrylic multifocal RAYNER IOL was implanted during phacoemulsification cataract surgery over a period of 21 months from October 2010 to June 2012. All patients were between 45 to 85 years of age. Routine pre-op evaluation and biometry using Topcon manual keratometer and Sonomed barometer were carried out. All the patients were operated by same surgeon using clear corneal incision 2.75 mm placed at steeper meridian. Patients with intra operative Anterior or posterior capsular rip were excluded from the study. Post-operative assessment was performed one day 1, 1 week, 1 month and every 6 months thereon. Minimum follow up was 6 months and ranged from 6 months to 21 months.
All 50 eyes had smooth Phaco and intra bag injection of IOLs with their recommended IOL Insertion System. Only five patients had bilateral implantation. All the IOLs were excellently centered intra-operatively and remained so in post op follow up. We had three unhappy patients, one because of residual astigmatism of -1.5D and the other one with no obvious reason. Third patient needed YAG 6 months post operatively and developed epithelial defect 2 weeks later leading to corneal nebula touching the visual axis. All of these patients are comfortable with both eyes open. We have planned LASEK for the first patient and the second one settled down 3 months post with a little delayed neuroadaptation. Rests of the patients were satisfied and happy with their own respective combinations.
Mixing and matching of Refractive Hydrophilic Acrylic RAYNER multifocal IOLs is possible in motivated well counseled patients. Refractive multifocal IOL Rayner 630F appears superior in our experience regarding centration and perfection in far and near vision.
