Pre- and post-operative precautions for highly myopic cataracts

Recently, the number of patients with high myopia combined with cataracts has been increasing. Compared with general age-related cataracts, the age of onset is relatively young, with increasing myopia and vision loss, requiring surgical correction. Compared with normal eyes, high myopia often has problems such as eye deformation, vitreous clouding, retinal thinning and high incidence of retinopathy. Compared with ordinary cataracts, preoperative and postoperative attention is needed: Preoperative: 1. If you have been wearing contact lenses for a long time, it is recommended to stop wearing them for 1-2 weeks before the preoperative examination to make the measurement data relatively accurate 2. If you have had laser or other myopia surgery or retinal surgery in the past, try to bring all the previous case information or inform the doctor to make the examination and surgery preparation more adequate and accurate.

Some patients may need to undergo fundus laser treatment before surgery. Do not drive or bike to the hospital for the preoperative examination, as the vision will be blurred for a few hours after the pupil dilatation to avoid inconvenience.

Some patients cannot see the fundus clearly before surgery due to cataract blockage, and if there are lesions in the fundus after surgery, laser treatment and follow-up may be required. Also during fundus examination and treatment, pupils need to be dilated, and try not to drive or ride to the hospital.

2, within six months after surgery, especially in the first 1-3 months try to avoid low head breath lifting heavy activities (including prolonged prone position massage, etc.) If there is a self-perceived increase in dark shadows in front of the eyes, partial visual field obscuration, visual distortion bending or vision loss, you need to come to the hospital in a timely manner. If there are no special circumstances, it is recommended to follow up the fundus at least once within one month, three months and six months after surgery.

3. Some patients with high myopia may be sensitive to surgery or postoperative hormonal eye drops, and postoperative IOP may fluctuate, so medication may need to be adjusted according to individual conditions.

4. If there is no abnormality after one eye surgery, the other eye surgery can usually be performed in 2-3 weeks. After the surgery, the previous glasses cannot be continued to be worn and the prescription needs to be adjusted. During the transition period, because the difference between the two eyes may be large, travel needs to pay attention to adaptation, up and down the step light should be slow.

5, generally about 2 months after surgery can be optometry prescription. The normal post-operative distance is generally about 30-35 cm. Patients with high preoperative myopia generally have a habit of looking very close to their eyes, and this habit needs to be adjusted appropriately to change.
