Experimental: Nd: YAG laser treatment Before treatment an optical coherence tomography (OCT) scan of the macula is performed to monitor possible macular oedema. After application of anesthetic and midriatics drops, the patient is positioned on the chin and forhead support (ND: YAG laser). Then, a contact lens (panfundoscope) is filled with methylcellulose and placed on the cornea. The laser is focused on the opacity that is to be treated and the first laser stamp of an initial power of 3 mJ is applied. The measured direct effect will guide in further adjustment of the laser beam power to achieve the desired effect. After treatment, a single drop of corticosteroid is applied to the patient and an ocular patch is applied. On follow up days an OCT scan of the macula is performed to monitor possible side effects. | Procedure: Nd: YAG laser treatment Before treatment an optical coherence tomography (OCT) scan of the macula is performed to monitor possible macular oedema.
