Vision problems during gestation are far more pervasive than what several females deem. Factually, ophthalmologists point out that corneal swelling occurs during pregnancy which can alter vision prescriptions among expectant mothers.
Cornea is translucent and having the shape of a dome, situated on the frontal part of the eye. It functions by refracting image to the backside of the eye where it is then conveyed on to the brain.
In case of a wrongly shaped cornea it impacts the manner in which focussing of an image is done on the backside of the eye which causes eyesight problems like short-sightedness or long-sightedness.
In spite of gestation-linked issues being rather prevalent, there are astonishingly no noteworthy studies done in this field. An alteration in amounts of progesterone (a hormone which dons a critical part all through gestation) might be having some kind of impact on a pregnant lady’s eyesight thus leading to vision problems.
Additional progesterone is necessary for softening collagen & cartilages in other regions of the body, like the pubis area, for assisting in foetal advancement down the vagina.
The conjecture is that additional progesterone impacts collagen presence in the corneal region. Unquestionably, corneal curvature occurs 
during gestational period that could be the reason for so many pregnant women developing eyesight problems like short-sightedness as a consequence.
Pregnant women even begin experiencing apparent dryness in their corneas which makes the use of contact lenses rather discomforting. This is because of the shortage of moisture.
At all times, the eye is enclosed by a fine fluid coat called the tear film which helps to lubricate the eyes, shield them from infections and in stabilizing eyesight. However this regulation is done by the lacrimal function-unit which gets impacted due to vacillating hormonal levels linked to gestation & nursing. The dryness felt might get additionally aggravated by the reality that expectant mothers or nursing females awaken during nights – times when there is innate dryness in the eyes.
For overcoming this problem, many ophthalmologists recommend using moisturizing eye drops. Another likely issue that pregnant women face is their lost capability of changing the spot of focus from close to far distance at-will – also called as accommodation. Physicians are unsure about the reason for this occurring; however there is some proof that the innate lens within the eyes looses some extent of suppleness.
But such alterations are generally transitory hence pregnant women are recommended to not undergo eye testing during gestation. Once the hormonal fluctuations normalize then eyesight and capability of focussing also retract to regular form.
However in around ten percent of cases it does not occur and one of the reasons cited is associated to late maternity.
There are an array of eye tests which are deployed – inclusive of pressure testing for excluding glaucoma condition (fluid accruement in the eyes that cause make a person blind).
Laser eye surgery is often the course of treatment for vision problems that arise during pregnancy and fail to subside post-gestation. But laser surgery on the eyes does carry complications like dryness in eye, photophobia (sensitiveness to light) & rather atypically, eyesight failure – hence choosing experienced and adept eye surgeons is of paramount importance.
Pre-procedure (twenty minutes pre-procedure) patients are given pain killers. The surgery commences with laser usage for making flaps in both corneas and on peeling them back the mid-section is revealed. Usage of one more laser is done for rectifying the irregularity in its form. Folding back of the flaps is then done into their earlier position and innately heals within 3 hours.
The therapy for correcting eyesight problems is just a 10 minute procedure – with just 5 minutes needed on every eye. Post-procedure, patients are recommended to rest in supine position with eyes shut for 3 hours. During this time, the patient is administered eye drops in fifteen minute time interval to aid in preventing infection.
At first, such patients post-procedure might sense slight dryness and warmth in their eyes though no pains. They are advised on donning sun glasses for the initial one day while their eyes heal and firstly recommended taking a bath instead of showering and steer clear from dust-ridden spots.
Post-procedure these patients are capable of reading without the need of their eye glasses.
