The brand new study compared the use of IOLs versus the usage of contact lenses during infancy for treating congenital unilateral cataract. In the United States most children with cataract will receive an IOL eventually, but the timing varies, Dr. Lambert said. ‘I've had patients wait until they were in college whereas others could have it done if they are 5 or 6 years old,’ he said. Some prior research suggested that using an IOL to treat cataract during infancy can improve long-term visual outcomes, he said. However, the use of IOLs during infancy also has some drawbacks. Surgeons have a problem judging the proper focusing power of the artificial lens for an infant, because it's a time of rapid eye growth. Also, while IOL implants are typically safe and complication-free of charge for adults, they are more likely to cause postoperative problems for infants.Increased heartrate and reduced heartrate variability in the first weeks of bereavement are feasible mechanisms of elevated cardiovascular risk in this often very demanding period, he stated.
