\n
\n

No. Presbyopia surgery with an intraocular lens replaces the natural lens that is beginning to become opaque. Therefore, it could be considered cataract surgery in its early stages, with the aim of eliminating the need for optical correction (whether glasses or contact lenses). <\/span><\/p>\n<\/div>\n<\/div>\n[\/vc_column_text][\/toggle][toggle color=”Default” heading_tag=”default” heading_tag_functionality=”default” title=”Is it permanent?”][vc_column_text]\n

\n

Yes. The implanted intraocular lens is permanent. If a small residual prescription remains, it can be corrected with laser. Only in exceptional situations is it necessary to remove the lens. <\/span><\/p>\n<\/div>\n[\/vc_column_text][\/toggle][toggle color=”Default” heading_tag=”default” heading_tag_functionality=”default” title=”Can I undergo surgery if I have already had surgery for myopia\/hyperopia\/astigmatism?”][vc_column_text]\n

\n
\n
\n

Of course. The cause of these refractive errors and the cause of presbyopia are completely different. Although all of these conditions result in the need to wear glasses or contact lenses, their origin is very different, so previous surgeries do not prevent presbyopia nor do they prevent its correction. <\/span><\/p>\n

CATARACT
\nSURGERY<\/strong><\/p>\n[\/vc_column_text][toggles style=”minimal”][toggle color=”Extra-Color-2″ heading_tag=”default” heading_tag_functionality=”default” title=”When should I undergo cataract surgery?”][vc_column_text]\n

\n

Cataract surgery is performed when the level of vision<\/strong> loss caused by the cataract begins to limit the patient\u2019s everyday activities.<\/strong><\/p>\n

This limiting vision loss usually occurs from 0.5 on the ophthalmological scale (sometimes even earlier). At this point, driving and even reading already become difficult.<\/p>\n<\/div>\n[\/vc_column_text][\/toggle][toggle color=”Default” heading_tag=”default” heading_tag_functionality=”default” title=”Can a cataract improve on its own so that I don\u2019t need surgery?”][vc_column_text]No. The development of cataracts is linked to aging and progresses irreversibly, so the only effective treatment is surgery.[\/vc_column_text][\/toggle][toggle color=”Default” heading_tag=”default” heading_tag_functionality=”default” title=”Does cataract surgery correct myopia\/hyperopia?”][vc_column_text]\n

\n
\n

Yes. When calculating the intraocular lens that replaces the natural lens during the surgery, it is adjusted to correct the patient\u2019s myopia or hyperopia<\/p>\n<\/div>\n<\/div>\n[\/vc_column_text][\/toggle][toggle color=”Default” heading_tag=”default” heading_tag_functionality=”default” title=”Does cataract surgery correct astigmatism?”][vc_column_text]Yes. There are several techniques to correct astigmatism during cataract surgery. One method involves making relaxing incisions<\/strong> that reduce astigmatism, while another uses special toxic lenses <\/strong>designed to correct it. In this case, the outcome is not as predictable as when correcting myopia or hyperopia, but astigmatism is generally significantly reduced.[\/vc_column_text][\/toggle][toggle color=”Default” heading_tag=”default” heading_tag_functionality=”default” title=”Will I have 100% vision after cataract surgery?”][vc_column_text]\n

\n

It depends on the condition of the other structures in the eye. The visual prognosis<\/strong> will be determined based on an examination prior to the surgery.<\/p>\n

A healthy ey<\/strong>e that has 100% vision and loses sight due to a cataract will regain that 100% after surgery. However, if, for example, due to retinal deterioration <\/strong>the eye could only see 60% and then loses vision because of a cataract, after lens surgery it will reach a maximum of that 60% vision.<\/p>\n<\/div>\n[\/vc_column_text][\/toggle][toggle color=”Default” heading_tag=”default” heading_tag_functionality=”default” title=”What intraocular lens will I be given?”][vc_column_text]\n

\n

The type of intraocular lens implanted is determined based on the patient\u2019s needs and daily activities.<\/p>\n
