If your near vision is good without glasses then your distance vision should be improved with glasses for myopia or nearsighted. Sometimes swelling of the cornea makes the eye temporarily myopic and the distance vision gets better over a week or two. The important thing to know is if the near vision is good glasses will help the distance vision. Don't do your other eye surgery until you are happy and pleased with this first eye surgery. If you end up more myopic than expected adjustments will need to be made in the calculations for what power IOL to use in the second eye.
Aside from temporary reasons your vision might be off at first as the doctor noted, there is the potential the lens power is off and left you nearsighted. There isn't an exact formula for determining lens power, it is an estimate best on statistics of eye measurements of past patients. Its usually fairly accurate for those with low prescriptions (but not always) but there is more of a risk of it being off for those with high prescriptions. During the first few weeks of healing the lens can move a bit inwards or outwards, making you more or less myopic, so they wait to be sure it is stable before figuring out how to address the situation. Usually for small errors they use a laser enhancement.
During the first few days after surgery, especially if there is still healing going on, there is more of a risk of temporary visual artifacts at night that are likely to go away. Most people don't have such visual artifacts, though sometimes it can take several weeks for them to subside (with any model of IOL) so there is no reason to panic yet.
If you have good vision at *any* distance, that means glasses/contacts can correct your vision and so you aren't in any way "legally blind", merely experiencing what highly nearsighted people live with when they aren't wearing correction. Before my surgery my nearsightedness left my best focal point at about 6.5 inches or so for my best eye. Obviously the point of RLE is to not need to wear correction, so if the issue doesn't resolve presumably you'll get a laser enhancement to correct it.
