Understanding IOL EXCHANGES

Some important basics about IOL Exchanges

If a person is undergoing intraocular exchange for a residual spectacle number, it is usually done after the age of 18 years. Occasionally patients not adjusting to multifocal IOLs needs an exchange with monofocal IOL. Selection of type of lens to be put in the second sitting depends on the eye condition and patient’s visual need for his routine activity. Now newer types of intraocular lens are available which can be put over the existing intraocular lens called piggyback lens (sulcoflex lens). The eye needs to be examined for suitability of such lens by an eye surgeon.
