Page "Geordi La Forge" Paragraph 14

During the Ba ' ku incident, La Forge began to experience pain in his eyes after sojourning on the planet.

Doctor Crusher removes his ocular implants to discover that his optic nerves have regenerated and he has gained normal sight.

This effect is caused by the healing properties of the Ba ' ku ring system and, at the time, it is speculated that the effect will fade after La Forge leaves Ba ' ku ( Star Trek: Insurrection ).

This diagnosis proved correct ; La Forge again wears the implants in Star Trek Nemesis.
