[Practical measures. Contact lenses after glaucoma surgery]

New soft therapeutic contact lenses after glaucoma surgery provide good results, both in terms of tolerance and efficacy (60% pressure increase in a personal series of ten patients with the Trabeculens contact lens). Indicated for moderate immediate postoperative leakage, their use remains transitory and they should be removed as soon as intraocular pressure is (rapidly) corrected. After glaucoma surgery, wearing contact lenses can be discussed if there are no contraindications and 6-12 months after the intervention in a compliant patient. Evaluation of the risk-benefit ratio is important. Gas-permeable, small-diatmeter hard contact lenses, bi- or trifocal spherical or posterior toric - the most stable - should be favored. Soft contact lenses can also be used, but because of their presence on the conjunctiva, notably in the filtration zone, they are less frequently recommended. Contact lens wear should in all cases be strictly limited to the daytime.
