Altitude will have no effect on the results of cataract surgery. However, certain types of retinal surgery may prevent you from flying at high altitudes or staying at high altitudes. The increase in intraocular pressure (IOP) and the decrease in IOP with leaking wounds are postoperative complications that optometrists should be prepared to treat. Research has shown that the severity of the damage is better correlated with the relative infusion pressure and not with the absolute level of IOP.
The corneal vertex lengthens due to the increase in the maximum deformation amplitude after cataract surgery. However, since the A2 time does not change while the deformation amplitude A2 is reduced, A2 Velocity accelerates after surgery. All patients underwent uncomplicated cataract surgery (removal of cataracts by phacoemulsification with intraocular lens (IOL) implantation in the back chamber) through a 2.8 mm temporary corneal incision (37 eyes of 37 patients) or an upper sclera-corneal incision of 2.8 mm (22 eyes of 22 patients). In cases where glaucoma is present, if IOP is elevated on the first day, it may be necessary to recheck their pressure at a short interval. The difference in the position of the lens may suggest a difference in the biomechanical properties of the eye, which can cause changes in IOP after cataract surgery.
Certain policies may exclude from coverage any medical expenses related to cataract surgery. Effects of high IOP and increased blood pressure from carbon dioxide on uveal and retinal blood flow in cats have been studied. However, the effects of cataract surgery on the ocular environment, such as aqueous humor or the vitreous cavity, are unknown. As more people undergo cataract surgery, optometrists must be prepared to address any perioperative needs that arise. Optometrists play an important role in treating patients with cataracts beyond simply diagnosing them and referring them to another eye doctor.
A weakened shock absorber can cause faster corneal movement from the maximum deformation at the moment HC to the deformation amplitude point A2, since energy applied to the eye (puff of air) is poorly absorbed. The A2 velocity, maximum strain amplitude, and maximum distance increased after cataract surgery, while the A2 strain amplitude and HC time decreased after surgery; these changes appear to be independent of changes in IOP. To combat mild eye dryness when flying after cataract surgery, artificial tears should be used frequently.
